A controlled conversion resin having an epoxy functionality of greater than 2 and comprising moieties derived from epoxy resin, dihydric phenol, acid anhydride, or amine. The resin is prepared by reacting an epoxy resin with a dihydric phenol, an acid anhydride, or amine or other branching agent in the presence of a catalyst and terminating the reaction at a point such that the reaction product contains both epoxy and terminal hydroxyl groups.
一种受控转化树脂,其环氧官能度大于 2,并包含由环氧树脂、二元酚、酸酐或胺衍生的分子。该树脂的制备方法是:在催化剂存在下,使环氧树脂与二水酚、酸酐或胺或其他支化剂反应,并在反应产物中同时含有环氧基和端羟基的位置终止反应。
