Abstract:
The present invention pertains to a method for producing a copolymer of ethylene and an allyl monomer having a polar group represented by general formula (1), or a copolymer of ethylene, an allyl monomer having a polar group represented by general formula (1), and other monomers, wherein the copolymer is produced in the presence of a boron compound having a boron-hydrogen bond or a boron-carbon bond (for example, a compound represented by general formula (2)) by using a metal complex represented by general formula (C1) as a polymerization catalyst (the symbols in the formulas are as described in the description). According to the present invention, a copolymer of ethylene and an allyl monomer can be efficiently produced with high catalytic activity, wherein the copolymer has a polar group and can be used in various applications.
