Polycarbodiimide compound, production process thereof, resin composition, and treatment method of article

Abstract

A polyfunctional polycarbodiimide compound contains at least four molecular chains bonded independently to a backbone. Each of the molecular chains contains a carbodiimido (—N═C═N—) group. The polyfunctional carbodiimide compound can be produced by reacting (a) an isocyanate compound having at least one carbodiimido group and at least one isocyanate group with (b) a polyol, polyamine and/or aminoalcohol having at least four hydroxyl, primary amino and/or secondary amino groups in a molecule. Also disclosed are a resin composition containing the polyfunctional polycarbodiimide compound as a crosslinking agent; and a treatment method of an article, which makes use of the resin composition.

Dependencies are inferred from the claim text.
