  3. 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

    研究了催化劑對環氧樹脂與氰酸酯樹脂的共固化反應行為的影響,並初步探索氰酸酯/環氧固化的反應歷程.研究表明,催化劑能明顯地促進其固化反應,降低固化溫度,縮短固化時間;氰酸酯與環氧共反應歷程是首先氰酸酯三反應生成三嗪環結構,然後三嗪環開環與環氧共反應,最後是未能參與共反應的環氧官能團在唑啉結構和三嗪環的催化下發生醚化反應;在氰酸酯官能團量的條件下,固化樹脂中主要是唑啉和醚結構,而三嗪環結構的含量很少
