| 摘 要： | 本文对聚(异氰脲酸酯-噁唑烷酮)(PISOX)的合成反应进行了系统研究.用原位红外法定量地研究了温度、投料比对PISOX合成中噁唑烷酮(OX)和异氰脲酸酯(IS)成环反应的影响规律.结果发现,低温有利于IS的生成,高温有利OX的生成;在高温下IS转化为OX;投料比与固化工艺决定着PISOX的结构.

| Abstract: | The formation of polyisocyanurate-oxazolidone(PISOX) has been systematically studied The influences of the reaction temperature and the ratio of isocynate and epoxy to the gene ration of oxazolidone(OX) and isocyanurate(IS) rings in the formation of PISOX were quanti fatively investigated by means of in-situ infrared spectroscopy. It is found that low tempera ture is suitable to the generation of IS ring and high temperature is favorable to the generatioi of OX ring. At higher temperature IS ring may open and transform into OX ring with epoxy group. The structure of PISOX is mainly deterrined by the ratio of isocynate and epoxy and also the curing technology. |
