The influence of catalyst on the copolymerization of epoxy and cyanate was investigated , and the mechanism of their copolymerization was discussed . the catalyst can obviously accelerate the curing of the resin to decrease the curing temperature . the three kinds of reactions ( cyclotrimerization , co - reaction and polyetherification ) in their copolymerization are not simultneous and independent to each other . in the lack of cyanate functional group , the main structures are oxazoine and polyether structure in the cured resin , and the triazine ring structure is of miner importance 研究了催化剂对环氧树脂与氰酸酯树脂的共聚固化反应行为的影响，并初步探索氰酸酯/环氧固化的反应历程.研究表明，催化剂能明显地促进其固化反应，降低固化温度，缩短固化时间；氰酸酯与环氧共聚反应历程是首先氰酸酯三聚反应生成三嗪环结构，然后三嗪环开环与环氧共聚反应，最后是未能参与共聚反应的环氧官能团在唑啉结构和三嗪环的催化下发生聚醚化反应；在氰酸酯官能团欠量的条件下，固化树脂中主要是唑啉和聚醚结构，而三嗪环结构的含量很少
