ALKOXYSILANE MODIFIED POLYAMIDE RESIN, ITS MANUFACTURING METHOD, HOT MELT ADHESIVE, AND RESIN CURED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide an alkoxysilane modified polyamide resin being excellent in heat resistance and mechanical strength, its manufacturing method, the hot melt adhesive and a resin cured article.;SOLUTION: The resin cured article obtained by curing an alkoxysilane modified polyamide resin obtained by reacting a terminal end isocyanate group-containing polyamide resin with an alkoxysilane compound represented by general formula (1), the terminal end isocyanate group-containing polyamide resin being obtained by reacting a polyester polycarboxylic acid obtained by a reaction of a multi-basic acid with a polyvalent alcohol with a polyisocyanate compound at a ratio that an isocyanate group becomes excessive relative to a carboxyl group is excellent in heat resistance and mechanical strength. (Wherein, R₁ represents 1-20C alkylene group, R₂, R₃ and R₄ are the same or different and represent a 2-20C alkoxy group or a 1-20C alkyl group, and at least one of R₂, R₃ and R₄ represents an alkoxy group).;COPYRIGHT: (C)2010,JPO&INPIT
