在过氧化物引发剂作用下 ,用角鲨烷模拟乙丙共聚物与马来酸酐进行接枝反应 .产物的质谱图显示产物中兼有马来酸酐自聚物和接枝产物 ,证明体系中存在着马来酸酐自聚和马来酸酐在角鲨烷上接枝一对竞争反应 ,马来酸酐在本实验条件下并不存在一个自聚上限温度 .核磁共振碳谱显示马来酸酐很大一部分是以单个分子接枝在角鲨烷上 ,并且没有固定的接枝点 ,可以接在次甲基上 ,也可以接在亚甲基上 ,但接在次甲基上的概率要大于接在亚甲基上 .
Under the action of peroxide initiator, the graft copolymer was reacted with maleic anhydride by using squalane analog ethylene-propylene copolymer.The mass spectrum of the product showed that the product contained both maleic anhydride self-polymer and graft product, There is a competition between maleic anhydride self-polymerization and maleic anhydride grafting onto squalane, and maleic anhydride does not have a self-limiting upper limit temperature under the experimental conditions. The NMR spectrum shows that the maleic anhydride is very large Part of a single molecule grafted in squalane, and there is no fixed point of grafting, can be connected to the methine, can also be connected to the methylene, but then connected to the probability of methine than the access On the methylene.
