CURABLE RESIN COMPOSITION
Document Type and Number:
Japanese Patent JPH04351626
Kind Code:
A
Abstract:
PURPOSE:To improve heat resistance, toughness, mechanical strengths, and water resistance by compounding a specific epoxy compd., a polyethersulfone, an arom. amine curative, and a radical polymn. initiator. CONSTITUTION:A condensate obtd. by condensing o-cresol with N- methylolacrylamide in the presence of an acid catalyst is reacted with epichlorohydrin in the presence of a phase transfer catalyst and then dehydrohalogenated with an alkali to give an epoxy compd. of formula I (wherein R is H or methyl). 100 pts.wt. the epoxy compd., 5-100 pts.wt. polyethersulfone of formula II (wherein X is a group selected from those of formulas III to VII), an arom. amine curative in an amt. of 0.5-2.0 amine equivalent based on 1 equivalent of epoxy groups, and 0.1-10 pts.wt. radical polymn. initiator are compounded.
