摘要

Abstract

A series of amorphous copolymers of ethylene and norbornene were prepared by polymerization with Zircorocenes of rac-Et (Ind)2ZrCl2MAO and Cp2ZrCl2/MAO. The Crystallinity decreases with the increase of norbornene contact in the copolymers. Glass transition temperature of the copolymer as high as 88 to 152 ℃ were determined by DSC

Intrinsic vianshes

[η] 0.04 to 2.73dl/g were measured in decalin at 135℃. The copolymer has a narrow molecular weight distribution (Mw/Mn) 2.0 to 25

meased by GPC in orthodichlorobenzene at 140℃.
