CATALYST FOR ETHYLENE POLYMERIZATION AND METHOD FOR PRODUCING ETHYLENIC POLYMER

摘要

The invention provides a polymerization catalyst comprising a post-metallocene complex with which it is possible to produce, with high activity, an ethylenic polymer having sufficient long-chain branching. Also provided is a method for producing an ethylenic polymer using this catalyst. The invention is a catalyst for ethylene homopolymerization or a catalyst for ethylene/a-olefin copolymerization comprising a complex represented by formula (1). The invention is also a method for producing an ethylenic polymer whereby ethylene is subjected to homopolymerization or ethylene and an a-olefin are subjected to copolymerization in the presence of the catalyst.
