Abstract
PURPOSE: To prepare a polyimide precursor having excellent adhesive properties to glass etc., by reacting a diamine with a carboxylic acid component comprising an organic tetracarboxylic acid and a specific polyvalent carboxylic acid modified by a silane.
CONSTITUTION: When reacting an organic tetracarboxlylic acid (A), an aminosilane compound (B) of formula I, where R1 is a divalent organic group containing a carbon atom directly bonded to Si; X is a hydrolyzable group such as alkoxy etc.; Y is alkyl, siloxy, etc., and an organic diisocyanate compound (C) of formula II, where R2 is a divalent organic group, a polyvalent carboxylic acid modified by a silane of formula III, where Tc4 is a tetravalent residual group of component A; Tc1 is a monovalent residual group of component A, is obtained by reacting one of two acid groups bonded to two adjacent carbon atoms of component A with an amino group of component B, the other of the two acid groups with an isocyanate group of component C, and further the residual isocyanate group of component C with component A. The titled precursor is obtained by the polymerization reaction of a carboxylic acid component comprising said polyvalent carboxylic acid modified by a silane and an organic tetracarboxylic acid with a diamine.
