Title:
WATER SOLUBLE BIODEGRADABLE POLYMER AND PROCESS FOR PREPARATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2012/042537
Kind Code:
A3
Abstract:
The present invention provides a water soluble biodegradable polymer and a process for preparation thereof. The polymer has characteristic NMR and FTIR peaks. The polymer is prepared by a process which comprises making a mixture of phosphatides and triglycerides, reacting the mixture with an anhydride in an organic solvent in presence of a catalyst at an elevated temperature for a duration ranging from one to three hours to obtain a reaction product, further hydrolyzing the reaction product, thereafter separating the solvent from the reaction product to obtain a mass, furthermore adding a second monomer with a catalyst to the mass, further curing the mass under stirring at reflux temperature for one to three hours, thereafter cooling the cured mass and neutralizing it with caustic lye to obtain the polymer. The polymer obtained by above mentioned process is biodegradable and has high calcium sequestration and calcium salt inhibition properties suitable as an additive for detergents and water treatment applications.
