摘要： The present invention relates to a method for producing a high-molecular-weight copolymer of polar group-containing allyl monomers comprising monomer units represented by formulae (3) and (4) (in the formulae, R 1 represents a hydrogen atom (H) or hydrocarbon group having 1 to 6 carbon atoms; R 2 represents -OH, -OCOR 3 (R 3 represents hydrocarbon group having 1 to 5 carbon atoms), -N(R 4 ) 2 (R 4 represents a hydrogen atom or hydrocarbon group having 1 to 5 carbon atoms); and n and m are a value representing the molar ratio of each of the monomer units), which has few branches and unsaturated group at the molecular end, by copolymerizing olefin and an allyl compound using a metal complex of group 10 elements in the periodic system represented by formula (I) as a catalyst.
The present invention enables providing a high-molecular-weight copolymer of polar group-containing allyl monomers, which copolymer has a novel structure, is available for various applications and has been considered to be difficult to synthesize by other polymerization methods such as radical polymerization; and a method for producing the same.-

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.-
