Title:
レジオイレギュラーなマルチブロックコポリマーを形成するための可逆的移動剤を含む触媒組成物
Document Type and Number:
Japanese Patent JP2008533275
Kind Code:
A
Abstract:
Copolymers, especially multi-block copolymer containing therein two or more segments or blocks, are prepared by polymerizing propylene, 4-methyl-1-pentene, or another C 4-8 ±-olefin in the presence of a composition comprising the admixture or reaction product resulting from combining:
(A) a first metal complex olefin polymerization catalyst,
(B) a second metal complex olefin polymerization catalyst capable of preparing polymers having increased incidence of regio-irregular branching compared to the polymer prepared by catalyst (A) under equivalent polymerization conditions, and
(C) a chain shuttling agent.
