摘要
Abstract
Three acrylate prepolymers were synthesized from hydroxyethyl methacrylate(HEMA),pentaerythri-tol triacrylate(PETA)or dipentaerythritol pentaacrylate(DPHA)and isophorone diisocyanate,reacting at a molar ratio of 1∶1.Then the prepolymers were grafted to phenolic vinyl ester resins by the catalysis of dibutyltin dilaurate(DBTDL).The heat distortion temperature(HDT),glass transition temperature(Tg),and thermal decomposition temperature of different acrylate grafted vinyl resins were studied.It is revealed that 20wt%DPHA prepolymer graft vinyl resin behaved the best heat resistant property,with HDT of 230℃,Tg of 220℃and 5wt%thermal decompo-sition temperature of about 330℃.关键词
