Title:
ETHYLENE/α-OLEFIN/NON-CONJUGATED POLYENE COPOLYMER, PRODUCTION METHOD THEREFOR, AND USE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2015/122495
Kind Code:
A1
Abstract:
Provided is a novel ethylene/α-olefin/non-conjugated polyene copolymer that has few long-chain branches and that comprises a constituent unit that is derived from: ethylene (A); an α-olefin (B) that has 3-20 carbon atoms; and a non-conjugated polyene (C) that contains a total of two or more partial structures that are selected from the group consisting of formulas (I) and (II) in a molecule thereof. The present invention makes it possible to provide a novel ethylene/α-olefin/non-conjugated polyene copolymer that contains a non-conjugated polyene such as VNB as a copolymer component, that contains few long-chain branches, and that has excellent curing characteristics when cross-linking is performed using a peroxide. The present invention also makes it possible to provide a production method for the ethylene/α-olefin/non-conjugated polyene copolymer and a use therefor.
