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.
In this paper, the synthesis of polyisocyanurate-oxazolidone (PISOX) was studied systematically.The in situ IR method was used to quantitatively study the effect of temperature and feed ratio on oxazolidoneone (OX) And isocyanurate (IS) .It was found that low temperature is conducive to the formation of IS and high temperature, which favors the formation of OX. IS converts to OX at high temperature. The charge ratio and curing process determine the structure of PISOX .
