Abstract
A modified carbodiimide resin obtainable by reacting a carbodiimide resin comprising a repeating unit represented by the general formula: —(NCN—R1)- wherein R1 represents a divalent organic group, with an aromatic diamine represented by the general formula: H2N—R2—NH2 wherein R2 represents a divalent organic group having a benzene ring, and a thermosetting resin composition comprising the modified carbodiimide resin and an epoxy resin.
Claims6
A guanidine-modified carbodiimide resin obtained by dissolving a carbodiimide resin consisting essentially of a repeating unit represented by the general formula:
- —(NCN—R1)- wherein R1 represents a divalent organic group, in a solvent to obtain a solution, and adding an aromatic diamine represented by the general formula:
- H2N—R2—NH2 wherein R2 represents a divalent organic group having a benzene ring, to the solution, thereby reacting the carbodiimide resin with the aromatic diamine in the solution.
