Novel 2-substituted-4,6-diamino-s-triazine/isocyanuric acid adduct, process for synthesis of said adduct and process for curing polyepoxy resin with said adduct

摘要

Disclosed is a 2-substituted-4,6-diamino-s-triazine/isocyanuric acid adduct represented by the following formula: <IMAGE> (1) wherein R stands for an alkyl group having 2 to 20 carbon atoms, an unsubstituted or cyano group-substituted aryl group, or a group of the formula R1-CH2CH2- in which R1 stands for an alkoxy group having up to 20 carbon atoms, an acyloxy group, an amino group, an N-substituted amino group, a benzotriazolyl group or a 2-alkylimidazolyl-(4)-dithiocarbonyl group, or by the following formula: <IMAGE> (2) wherein R2 stands for an alkylene group which may have an intervening imino or phenylene group. When this adduct is used for curing a polyepoxy resin, a cured product having good heat resistance, insulating property and adhesion and an excellent migration-preventing effect is formed.
