| abstract |
This invention is a novel ethylene. α-olefin. A non-conjugated polyene copolymer having ethylene (A), an α-olefin (B) having 3 to 20 carbon atoms, and a total of two or more molecules selected from the group consisting of the following general formula (I) and ( II) The constituent units of the partially-constructed non-conjugated polyene (C) in the group formed by the group, and there are fewer long-chain branches.nn n n n n n n n n n According to the present invention, it is possible to provide a novel ethylene containing non-conjugated polyene such as VNB as a copolymerization component, having a small content of long-chain branches, and having excellent hardening characteristics when crosslinked using a peroxide. α-olefin. Non-conjugated polyene copolymers, in turn, can provide the ethylene. α-olefin. Production method and use of non-conjugated polyene copolymer. |
