摘要
Diamines of the Structure wherein X is -SO₂- or -CO-, Y is O or S, and Ar is a linear aryl ether moiety comprising from 1 to 80 aryl rings, are epoxy resin curing agents providing cured resins with improved moisture resistance and toughness. The resins are particularly useful in preparing prepregs and composites.
