【摘要】 本文论述了在相转移催化剂存在下双酚-s型环氧树脂的合成。该反应是以双酚-s、环氧氯丙烷为原料,用乙醇作溶剂、在碱及相转移催化剂聚乙二醇存在下完成的。产物为白色粉沫状,其特性粘度为4—10(ml/g)。更多还原

【Abstract】 Bisphenol-sepoxy resin has been synthesized with phase transfer catalysis. The method involes the reaction of Bisphenol-s with epichlorohydrin in a aqueous alkiethyl alcohol system, at 80c-95c. The polyethlene glycols are used as phase transfer catalysis, the product is odtained in the form of powder, its intrinsic viscosity is 4-10 (ml/g) ,更多还原
