Title:
OLEFINIC POLYMER AND MANUFACTURING PROCESS THEREFOR
Document Type and Number:
Japanese Patent JP2004359798
Kind Code:
A
Abstract:
To obtain a block copolymer consisting of an α-olefin-cyclic olefin copolymer unit and to provide a process for manufacturing the block copolymer with a high polymerization activity.
The olefinic copolymer contains the α-olefin-cyclic olefin copolymer blocks comprising (A)constitutional units of two or more kinds having different cyclic olefin contents derived from 2-30C straight chain or branched α-olefins and (B) a constitutional unit derived from a specific cyclic olefin expressed by formula (1).
