摘要
环氧丙烷聚醚是以 -OH为端基 ,当作为增韧剂与环氧树脂反应时 ,活性较小。通过将聚醚二端引入环氧基团 ,制备聚醚类二缩水甘油醚 ,以提高聚醚类增韧剂的增韧性和反应活性。
Polypropylene glycol(PPG)terminated with two hyroxyl groups used in epoxy resin as toughening agent had lower reactivity with epoxy resin than polypropylene glycol diglycidyl ether(PPGDGE).In this paper the synthetic process of the latter was studied.The factors and product properties were also tested and showed that PPGDGE was a perfect toughening agent to epoxy resin.
