    摘要： A method for coating the surface of a substrate composed of a hydrophobic polymer with a hydrophobic vinyl polymer. The method includes preparing a solution of the hydrophobic vinyl polymer in a polar nonaqueous solvent, such as 1-methyl-1-pyrrolidinone, in which the hydrophobic vinyl polymer is surface-active. The substrate then is treated with the solution under conditions sufficient to deposit the hydrophobic vinyl polymer on the substrate. The hydrophobic vinyl polymer may have readily hydrolyzable pendant groups which, upon hydrolysis thereof in an aqueous medium, will result in the formation of a hydrophilic vinyl polymer coating on the substrate. For example, the hydrophobic vinyl polymer may be poly(vinyl trifluoroacetate). Also provided are coated substrates, in which the substrate is a shaped article composed of a hydrophobic polymer. The shaped article may be, for example, a film, fiber, or nonwoven web.

    摘要： A resin composition, comprising: a polyolefin (A); a saponified ethylene-vinyl acetate copolymer (EVOH) (B) having an ethylene content of 20 to 65 mol% and having a degree of saponification of vinyl acetate units of 96% or more; a higher fatty acid metal salt (C) having 8 to 22 carbon atoms; a conjugated polyene compound (D) having a boiling point of 20° C. or higher; an ethylene-vinyl acetate copolymer (E); and a saponified ethylene-vinyl acetate copolymer (F) having an ethylene content of 68 to 98 mol% and having a degree of saponification of vinyl acetate units of 20% or more, wherein the mass ratio (A:B) of the polyolefin (A) and the EVOH (B) is 60:40 to 99.9: 0.1, the amount of the higher fatty acid metal salts (C) is in the range of 0.0001 to 10 parts by mass per 100 parts by mass of the total of the polyolefin (A) and the EVOH (B), the amount of conjugated polyene compound (D) is in the range of 0.000001 to 1 part by mass, and the total amount of the ethylene-vinyl acetate copolymer (E) and the saponified ethylene-vinyl acetate copolymer (F) is 0.3 part by mass or more. This enables improvement of poor appearance of a molded article caused by insufficient dispersion of the EVOH (B) at the time of melt molding a resin composition comprising the polyolefin (A) and the EVOH (B).
