α-OLEFIN/CYCLIC OLEFIN COPOLYMER AND ITS MANUFACTURING METHOD

Title:

α-OLEFIN/CYCLIC OLEFIN COPOLYMER AND ITS MANUFACTURING METHOD

Document Type and Number:

Japanese Patent JP2002332312

Kind Code:

A

Abstract:

To obtain an α-olefin/cyclic olefin copolymer having a very narrow molecular weight distribution, and to provide a method for manufacturing this α-olefin/cyclic olefin copolymer with high polymerization activity.

The α-olefin/cyclic olefin copolymer consists of (A) at least one constituting unit selected from the group consisting of 2-30C linear or branched α-olefins and (B) at least one constituting unit selected from the group consisting of cyclic olefin-derived constituting units and has (a) an Mw/Mn obtained by GPC of 1.0<(Mw/Mn)≤1.8, (b) a weight average molecular weight (Mw) of 1,000≤Mw≤5,000,000, and simultaneously, (c) a molar ratio of the constituting unit derived from the α-olefin to that derived from the cyclic olefin of 99/1 to 20/80.
