TECHNICAL FIELD The present invention relates to a multi-cationic polymer having a block cationic polyelectrolyte site. The pèsent invention further relates to suitable methods of making the multi-cationic polymer.

BACKGROUND High molecular weight materials are used in various fields of industry.

Some general uses of these materials include use as structural materiais or composite materials, for coating, covering, barrier, and delivery.

However, many high molecular weight material generally have poor adhesion to surfaces such as fabrics, hair and skin, glass, metals, and filler materials. It is known in the art that such surfaces are generally slightly negatively charge. Material having positive charges are expected to have better deposition on such surfaces.

Polymers having multi-cationic sites are known in the art, such as in Saegusa et al."Catalysis of Polymers Containing Quaternized Linear Poly (N- alkylethyleneimine) Chain in Aqueous-Organic Hetero-Phase Rections" Polymer Journal, Vol. 11, No. 1, pop1-6, issued 1979.

Based on the foregoing, there is a need for a polymer which has good adhesion to various surfaces, and thus suitable for use in products required to have good deposition to surfaces.

None of the existing art provides all of the avantages and benefits of the present invention.

Abs. triethylamine and abs. pyridine act both as a solvent and a liquid Lewis base, and thus suitable. Abs. triethylamine is a highly suitable liquid Lewis base. More preferably, the medium contains at least a stoichiometric amount to the activating agent of a Lewis base, as it provides good yield. Still preferably, the medium contains: a volatile solvent such as abs. THF, abs. benzene, abs. toluene and mixtures thereof; and a stoichiometric amount to the activating agent of a liquid Lewis base such as abs. triethylamine, abs. pyridine, and mixtures thereof.

The activated starting polymer either obtained by the preliminary rection or obtained commercially is polymerized through a rection known as ring- opening polymerization, an embodiment of which is shown in the following scheme: This can be done by subjecting the activated starting polymer as exemplified by formula (ICI) with a cyclic iminoether to obtain a polyamide intermediate exemplified by formula (IV). The cyclic iminoether is selected from the group consisting of 2-substituted-2-oxazoline, 2-substituted-5,6-dihydro-4H1,3-oxazine, and mixtures thereof. Preferable cyclic iminoethers are 2-Z'-2-oxazoline and 2-

Z'-oxazine wherein Z'is a hydrogen, alkyl, or fluorocarbon having 1 to 10 carbons, phenyl and benzyl, still preferable are 2-alkyl-2-oxazoline wherein the alkyl is made of 1 to 3 carbons, as exemplified as formula (XII). The tosyl, mesyl or halide group of the activated starting polymer (III) is known to be a leaving group on the attack by various nucleophilic monomers. The tosyl and mesyl groups are preferable leaving groups. Thus, the activated starting polymer (ICI) is utilized as a macromolecular initiator for the synthesis of a block copolymer through nucleophilic rection toward the tosylate or mesylate ester function or halide at the functionality by the cyclic iminoether which acts as a nucleophilic monomer. The polyamide intermediate (IV) thus obtained has concentrated polyamide moities at functionalities of the polymer which had originally been activated.

Suitable mediums for carrying out this first stage of synthesis include inert solvents which provide an anhydrous condition. Exemplary inert solvents are abs. acetonitrile, abs. THF, abs. benzene, abs. toluene, abs. triethylamine, abs. pyridine, and mixtures thereof. Preferably, the medium contains a Lewis base.

Exemplary Lewis bases include those which are liquid and solid such as abs. triethylamine, abs. pyridine, dimethylamino pyridine (hereinafter referred to as "DMAP"), and 1,8-diazabicyclo [5.4.0.]-7-undecene (hereinafter referred to as "DBU"). Abs. triethylamine and abs. pyridine act both as a solvent and a liquid Lewis base, and thus suitable. Abs. triethylamine is a highly suitable liquid Lewis base. More preferably, the medium contains at least a stoichiometric amount to the activated starting polymer as exemplified by activated siloxane (ICI) of a Lewis base. It has been found that the existence of this amount of Lewis base significantly raises the conversion yield of the activated starting polymer to the resulting polyamide intermediate. Thus, the number of amide moities of the present polymers (number"m"in the structure) can be controlled with significantly improved precision to p (ovide the targeted polymer at high yield.

Still preferably, the medium contains: a volatile solvent such as abs. acetonitrile, abs. THF, abs. benzene, abs. toluene and mixtures thereof; and a stoichiometric amount to the activating agent of a liquid Lewis base such as abs. triethylamine, abs. pyridine, and mixtures thereof. A highly preferred medium is an acetonitrile solution of at least a stoichiometric amount to the activated starting polymer of abs. triethylamine. The rection can be carried out at room temperature or elevated temperature at around atmospheric pressure.

After the ring-opening polymerization is completed, the obtained reactant is treated with an alkali or alkali salt to obtain the polyamide intermediate (IV).

Such alkali or alkali salt include sodium carbonate, sodium hydrogen carbonate, potassium carbonate, potassium hydrogen carbonate, amines in an inert solvent, and metal or tetra-alkyl ammonium salts of organic acids. When the reactant is treated with aqueous alkaline such as sodium carbonate, the finally obtained polymer will have a hydroxy terminal. When the reactant is treated with amines in an inert solvent, the finally obtained polymer will have amine or ammonium terminated terminals. When the reactant is treated with salts of organic acids, the finally obtained intermediate will have carboxylate or ester terminals.

REDUCTION OR HYDROLYSIS The second stage comprises reduction or hydrolysis of the obtained polyamide intermediate (IV).

Reduction can be done, for example, by reacting the polyamide intermediate with a reducing agent such as LiAI (OR) xH4-x wherein R is methyl, ethyl, or isopropyl, and x is 0 or an integer from 1 to 3; preferably LiAIH4 (lithium aluminum hydride) to obtain a reduced polyamide intermediate as exemplified by formula (\/) as shown in the following scheme: Suitable mediems for carrying out such reduction include inert solvents such as abs. THF and abs. diethylether. Reduction can be alternatively done by reacting the polyamide polymer with an agent such as (C2Hs) 3O+BF4-, C13SiH, C13SiOH, C13SiOCH3, C13SiOC2H5, (CH3) 3SiCI, or dimethylsulfate in an inert solvent such as n-hexane or CH2CI2, followed by treatment with NaBCNH3or NaBH4 in diethylether, ethanol, or THF.

Hydrolysais can be done, for example, by reacting the polyamide intermediate with aqueous and alcohol/aqueous solutions of strong acids and alkalis such as HCI, NaOH, KOH, or NaHC03 to obtain a hydrolyzed polyamide intermediate as exemplified by formula (VI) as shown in the following scheme: Hydrolysis can be alternatively done by reacting the polyamide intermediate with an agent such as (C2H5) 30+BF4-, Cl3SiH, CIgSiOH, Cl3SiOCH3, Cl3SiOC2H5, (CH3) 3SiCl, H2N-NH2, or dimethylsulfate in an inert solvent such as n-hexane abs. THF, diethylether or CH2CI2, followed by treatment with diluted aqueous solutions of acids and alkalis such as HCI, NaOH, KOH, NaHCO3, K2CO3.

Na2CO3, or KHC03.

QUATERNIZATION The third stage comprises quaternization of the obtained reduced polyamide intermediate (V) or hydrolyzed polyamide intermediate (VI) to obtain a multi-cationic polymer of the present invention. This can be carried out by adding a quaternizing agent. Quaternizing agents are selected from the group consisting of monomethylsulfuric acid, dimethylsulfate, diethylsulfate, dimethylcarbonate, methylchloride, methyliodide, methylbromide, ethylchloride, ethyliodide, ethylbromide, benzylchloride, benzylbromide, benzyliodide, sulfuric acid, carboxylic acid, hydrochloric acid, hydrobromic acid, hydroiodic acid, and mixtures thereof. It is known in the art that, when quaternization is conducted with quaternizing agents which provide positively charged alkyls such as monomethylsulfuric acid, dimethylsulfate, diethylsulfate, dimethylcarbonate, methylchloride, methyliodide, methylbromide, ethylchloride, ethyliodide, ethylbromide, benzylchloride, benzylbromide, and benzyliodide, the quaternized cite is stable and pH independent. Quaternization which provides positively charged alkyls is exemplified by the following scheme:

X5-= mixture of anions selected from the group consisting of S042-, HS04-, and CH3SO4- On the other hand, when quaternization is conducted with quaternizing agents which provide, protons to the amine moiety such as sulfuric acid, carboxylic acid, hydrochloric acid, hydrobromic acid, and hydroiodic acid, the quaternized cite is pH dependent.
