二烯丙基二苯并噁嗪中间体的结构与固化行为
STRUCTURE AND CURING BEHAVIOR OF A NEW DIBENZOXAZINE PRECURSOR CONTAINING ALLYL GROUP
【摘要】 苯并嗪化合物是以酚类化合物、胺类化合物和甲醛为原料合成的六元杂环.在适当条件下能发生开环聚合反应,生成类似于酚醛树脂结构的材料,固化过程无低分子挥发成份放出,因而作为酚醛树脂高性能化的新途径,日益受到人们的重视并得到了应用[1~3].苯并嗪化合物...
【Abstract】 The composition,structure and cyclic ratio of diallyl dibenzoxazine (DADBOZ) prepared by suspension method were characterized by FTIR and 1H_NMR.A combination of DTA,FTIR was used to investigate the curing reaction of DADBOZ precursor at different conditions.The DADBOZ precursor is composed of two kinds of reactive functional groups:one is benzoxazine ring and another is allyl group,which can be cured through ring opening polymerization or addition polymerization at different situation,Therefore,different polymer structures can be obtained.
