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.
