Title:
CATALYST FOR OLEFIN POLYMERIZATION AND METHOD FOR PRODUCING OLEFIN POLYMER
Document Type and Number:
WIPO Patent Application WO/2023/037849
Kind Code:
A1
Abstract:
Provided are a catalyst, which enables the production of a high molecular weight olefin polymer having a polar group and being usable for various applications at a high catalytic activity, and a method for producing such an olefin polymer. Use is made of, as a polymerization catalyst for an olefin having a polar group, a metal complex represented by general formula (C1) [wherein: M represents an element in group 10 of the periodic table; X represents a phosphorus atom (P) or arsenic atom (As); R5 to R11 are as described in claims; at least one of R6 and R7 is an aralkyl group represented by general formula (2) (wherein R12 to R21 are as described in claims); L represents an electron-donating ligand; and q is 0, 1/2, 1 or 2].
