摘要
通过烯烃(尤其是乙烯和丙烯)均聚合的方式制备弹性体,不仅可以大幅度简化生产工艺,降低生产成本,还可以制备新型结构的聚烯烃材料,赋予聚烯烃材料新的功能和用途。系统阐述了烯烃均聚合制备弹性体的研究进展,对用于制备无规聚丙烯、超支化聚乙烯、立构嵌段聚丙烯及嵌段聚乙烯的催化体系和聚合条件进行了详细的介绍。对目前这个研究领域还存在的问题进行了剖析,提出了这一研究领域的设想和展望。
Preparation of elastomers by homopolymerization of olefin（especially ethylene and propylene）can not only greatly simplify the production process（reducing production costs）,but also provide polyolefin materials with new structure（endowing polyolefin materials with new function and application）.In this paper,the research progress of preparation of elastomers by homopolymerization of olefin was systematically described.The catalytic system and polymerization conditions for preparing atactic polypropylene,hyper-branched polyethylene,steric block polypropylene and block polyethylene,respectively,were introduced in detail.The existing problems in this field were analyzed,and the ideas and prospects of our own in this field were put forward.
