摘要： 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.

摘要： The present invention relates to a gas-barrier resin composition, including: a gas-barrier resin (A) having an oxygen permeability coefficient of 1.0×10 -14 (cm 3 ·cm/cm 2 ·s·Pa) or less; and a copolymer (B) containing monomer structural units represented by the formula (1), the formula (2), and the formula (3):
where: R 1 represents a hydrogen atom or a methyl group; R 2 represents a hydrocarbon group having 1 to 20 carbon atoms that may be substituted with a halogen atom, a hydroxy group, an alkoxy group, or an amino group; l, m, and n represent numerical values representing molar proportions of the respective monomer structural units, and n may represent 0; and p represents an integer of from 1 to 4, wherein a ratio of a mass of the copolymer (B) to a total mass of the gas-barrier resin (A) and the copolymer (B) is from 1 mass% to 40 mass%. Preferred as the gas-barrier resin (A) are a vinyl alcohol-based resin (A1), a polyamide-based resin (A2), and a polyester-based resin (A3). The present invention can provide a resin composition ameliorated in low flexibility and low impact resistance, which are drawbacks of a gas-barrier resin, without impairing excellent gas barrier properties of the gas-barrier resin.
