Title:
METHOD FOR PREPARING OLEFIN-POLAR MONOMER COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2021/083358
Kind Code:
A1
Abstract:
Disclosed are a method for preparing an olefin-olefinic alcohol copolymer and an olefin-vinyl alcohol copolymer prepared by the method. The catalyst used in the method for preparing the olefin-olefinic alcohol copolymer comprises a diimine metal complex as shown in Formula I. The spherical and/or spherical-like polymer prepared according to the preferred embodiment of the preparation method has good prospects in industrial applications.
