Title:

OLEFIN COPOLYMER, FILM, AND SHEET

Document Type and Number:

WIPO Patent Application WO/2001/030870

Kind Code:

A1

Abstract:

An olefin copolymer obtained from [A] a cycloolefin, [B] an aromatic vinyl compound, and [C] a C¿2-20? aliphatic $g(a)-olefin, wherein (1) the content of units derived from the ingredient [A] is 0.1 to 30 mol%, that of units derived from the ingredient [B] is 0.1 to 49.9 mol%, and the sum of the units of the ingredient [A] and the units of the ingredient [B] is 0.2 to 50 mol% and (2) the glass transition temperature Tg is below 60°C. The olefin copolymer is suitable for use as a novel flexible resin having moderate modulus which makes the resin usable as a substitute for soft polyvinyl chloride and further having excellent elastic recovery and transparency.
