The useful pot life of epoxide compositions containing a phenyldiazonium hexafluorophosphate as a latent polymerization catalyst is appreciably extended when the diazonium compound contains one or more alkoxy or benzyloxy radicals as substituents on the phenyl radical. The substituents are preferably located on carbon atoms that are ortho or para with respect to the carbon atom bearing the diazonium radical.
含苯基重氮六氟磷酸盐作为潜在聚合催化剂的环氧组合物的有用使用寿命在重氮化合物的苯基上含有一个或多个烷氧基或苄氧基取代基时,可以明显延长。 取代基最好位于与带有重氮基团的碳原子相对的邻位或对位碳原子上。
