研究了苯并恶嗪与氰酸酯树脂的固化反应及固化物的性能。特别是氰酸酯树脂的含量对固化行为和固化的新型热固性树脂的性能的影响进行了研究。结果发现，发生苯并恶嗪环的开环反应和氰酸酯基的热自环三聚，然后由苯并恶嗪环的开环反应产生的酚羟基可能与氰酸酯基共反应。随着氰酸酯树脂含量的增加，凝胶化反应进行得更快。由苯并恶嗪与氰酸酯树脂固化而成的新型热固性树脂具有良好的热稳定性、高电阻率和高耐水性。随着氰酸酯树脂含量的增加，玻璃化转变温度和电阻率变得更高。(c)2012 Wiley Periodicals，Inc.

A curing reaction of benzoxazine with cyanate ester resin and the properties of the cured new thermosetting resin were investigated. In particular, the effect of the content of cyanate ester resin on the cure behavior and the properties of the cured new thermosetting resins were investigated. As a result, it was found that the ring-opening reaction of a benzoxazine ring and thermal self-cyclotrimerization of a cyanate ester group occurred, then the phenolic hydroxyl group generated by the ring-opening reaction of the benzoxazine ring might coreact with the cyanate ester group. As the content of cyanate ester resin increased, the gelation reaction proceeded more quickly. The cured new thermosetting resin from benzoxazine and cyanate ester resin showed good thermal stability, high electrical resistivity, and high water resistance. As the content of cyanate ester resin increased, the glass transition temperature and electrical resistivity became especially higher. (c) 2012 Wiley Periodicals, Inc.
