Document Type and Number:
WIPO Patent Application WO/2018/092752
Kind Code:
A1
Abstract:
Provided are: a polycarbodiimide copolymer and a modified polycarbodiimide copolymer, which are suitable as a curing agent capable of improving flexibility without impairing water resistance in a cured product of a carboxyl group-containing resin composition; a curing agent for a carboxyl group-containing resin composition; and a carboxyl group-containing resin composition. The present invention, when used as a curing agent, can improve the water resistance of a cured product by introducing a predetermined soft segment into the polycarbodiimide molecule, and can improve the storage stability of the carboxyl group-containing resin composition by modifying the resin composition with an aliphatic amine or an aromatic heterocyclic amine.
