引言现代的高分子领域,在着重对已有的通用高分子和特种高分子进行应用基础研究的同时,还重视开发新的聚合方法,从而达到高分子设计最佳化。因此,国外对新的聚合方法进行了广泛的研究。近期报道的新聚合方法不少是有理论和经济价值的,诸如脱氢聚合、氧化聚合、氢移位聚合、开环聚合、闭环聚合、异构化聚合、重排聚合、固态聚合、晶相聚合、旋光活性聚合及管道、模板聚合等等。选择聚合虽然在1948年的化学文献中提到过,但当时主要指丁烯馏份中异丁烯的二聚。更深入细致的工作是近年来开始的,并且得出了有实用价值的结果。选择聚合是以不同组份的混合物为原料,在反应前不经任何分离而产生所希望的产品。这样可简化工艺、节约能量、原材料及设备,
Introduction In the field of modern polymer, while focusing on the applied basic research of common polymers and specialty polymers, we also attach importance to the development of new polymerization methods to achieve the optimization of polymer design. Therefore, foreign countries have conducted extensive research on new aggregation methods. Recently, many new polymerization methods reported have theoretical and economic value, such as dehydrogenation polymerization, oxidative polymerization, hydrogen shift polymerization, ring opening polymerization, ring closure polymerization, isomerization polymerization, rearrangement polymerization, solid state polymerization, crystalline phase Polymerization, optically active polymerization and pipelines, template polymerization and more. Although the polymerization was mentioned in the chemical literature of 1948, it was mainly the dimerization of isobutylene in the butylene fraction. More in-depth and meticulous work began in recent years, and come to practical results. The choice of polymerization is a mixture of different components as raw materials, before the reaction without any separation to produce the desired product. This will simplify the process, save energy, raw materials and equipment,
