A vinyl ester resin is derived from the reaction of an unsaturated acid with an epoxy terminated polymer made from a dithio or a trithio initiator, and optionally from an epoxy resin. The vinyl ester resin can be blended with a miscible toughener and a diluent to provide a time stable system and subsequently crosslink to provide a composition with improved toughening properties.
一种乙烯基酯树脂是由不饱和酸与由二硫或三硫引发剂制成的环氧末端聚合物反应而得的,可选地还包括环氧树脂。这种乙烯基酯树脂可以与相容的增韧剂和稀释剂混合,以提供一个时间稳定的体系,随后交联以提供具有改善增韧性能的组合物。
