摘要
烯烃聚合过程中,金属化合物之间快速可逆的链转移反应是一个重要和有用的反应,它不仅影响催化剂的活性和实现对聚合物分子量的控制,还可以得到长链烷基金属化合物,进而通过后续转化得到特种聚烯烃材料,如官能团化聚烯烃和多嵌段聚烯烃共聚物.综述了这一方面的主要发展情况.
During olefin polymerization process, a rapid and reversible chain transfer reaction between the metal complexes is of great importance. This reaction not only affects the activity of the catalytic system and the molecular weight of the polymer but also provides the metal complex with long alkyl chain, which can be used in the preparation of some high quality polyolefins, such as functionalized polyolefins and olefin multiblock copolymers. This review describes the major advances in this field.
