Title:

ETHYLENE/Α-OLEFIN/NON-CONJUGATED POLYENE COPOLYMER, USE THEREFOR, AND MANUFACTURING METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2015/122415

Kind Code:

A1

Abstract:

The purpose of the present invention is to obtain an ethylene/α-olefin/non-conjugated polyene copolymer that has a low permanent compression set at low temperatures, is flexible, and has an excellent balance of rubber elasticity at low temperatures and tensile strength at normal temperatures. This ethylene-based polymer is an ethylene/α-olefin/non-conjugated polyene copolymer that includes units derived from ethylene (A), units derived from an α-olefin (B) containing 4-20 carbon atoms, and units derived from a non-conjugated polyene (C) and satisfies (1)-(4). (1) The molar ratio of (A) to (B) is 40/60-90/10, (2) the contained amount of the units derived from (C) is 0.1-6.0 mol%, (3) ML(1+4)125°C is 5-100, and (4) the B value is 1.20 or more.
