Japanese Patent JP2728304
Kind Code:
B2
Abstract:
This invention relates to a novel polyaldimine, preparation process of the polyaldimine, moisture curable polyurethane composition containing the polyaldimine and use of the composition. Polyaldimine of this invention is represented by the formula (I): wherein R<1>, R<2> and R<3> are a halogen atom, hydrogen atom, alkoxy group having 4 or less carbon atoms or an alkyl group having 5 or less carbon atoms, and may be the same or different; R<4> is a hydrogen atom or a methyl group; Y is -N=CH-C(R<5> )3 or -N=CH-C(CH3 )2-CH2-O-CO-R<6> wherein R<5> is an alkyl group having 4 or less carbon atoms, R<6> is an alkyl group, anilino group, benzylamino group or an alkylamino group having 16 or less carbon atoms; and l is an integer of 1 or 2, m is an integer of 1 to 3, and n is an integer of 0 to 300. Polyaldimine is prepared by condensation of the corresponding aromatic polyamine and aldehyde. A moisture curable polyurethane composition is prepared from the above polyaldimine and organic polyisocyanates. Sealing materials, wall covering materials, water proof materials and flooring materials can be prepared by blending thixotropic agents or fillers with the polyurethane composition. These materials have very good storage stability and are rapidly cured by atmospheric moisture and cured polyurethane resin having excellent properties can be obtained.
