The present invention provides a polyolefin copolymer in which an olefin monomer is graft-copolymerized to modified particles of a metallic compound. The polyolefin graft copolymer can be obtained by graft-copolymerizing the olefin monomer to modified particles of a metallic compound in the presence of a coordination polymerization catalyst in the presence of, particularly, a coordination polymerization catalyst of a late transition metal complex. Further, the property of a polyolefin resin can be improved by blending the polyolefin graft copolymer to a polyolefin resin.
本发明提供了一种聚烯烃共聚物,其中烯烃单体与金属化合物的改性颗粒进行接枝共聚。该聚烯烃接枝共聚物可通过在配位聚合催化剂(尤其是后期过渡金属络合物的配位聚合催化剂)存在下,将烯烃单体接枝共聚到金属化合物的改性颗粒上而获得。此外,通过将聚烯烃接枝共聚物与聚烯烃树脂混合,可以改善聚烯烃树脂的性能。
