聚烯烃与极性聚合物的嵌段与接枝

Progress in Blocking and Grafting of Polyolefin and Polar Polymer

将聚烯烃与极性聚合物共价键相连制成嵌段或接枝共聚物可对聚烯烃进行功能化改性。介绍了嵌段型聚烯烃-极性聚合物制备的活性配位聚合法、跨机理聚合法和大分子偶联法,以及接枝型聚烯烃-极性聚合物制备的偶联接枝法、引发接枝法和大单体共聚接枝法。列举了主要研究进展,并从产品可工业化制备的角度评述了各方法的特点。

Blocking or grafting of polyolefin with polar polymer can be used to functionalize the polyolefin.In this review,the methods for preparation of the block copolymers such as living coordination polymerization,traversing polymerizations from coordination polymerization and coupling of macromolecules with reactive terminal group,and the methods for preparation of the graft copolymers such as grafting onto,grafting from and grafting through were introduced.Their research progress and application prospect in industry were presented.
