    摘要: A resin composition, comprising: apolyolefin (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 200 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).

    摘要: A polypropylene resin composition contains 2 to 15 wt % of a moldability improver (A) and 85 to 98 wt % of a polypropylene resin (B). The moldability improver (A) is formed of propylene block copolymers (A-1) and (A-2). Each of the propylene block copolymers (A-1) and (A-2) has a crystalline propylene polymer component (A-11), (A-21) and a propylene-ethylene random copolymer component (A-12), (A-22). The propylene block copolymer (A-1) is characterized in that the melt flow rate of the crystalline propylene polymer component (A-11) is high, whereas the propylene block copolymer (A-2) is characterized in that the content ratio of the propylene-ethylene random copolymer component (A-22) is high. The polypropylene resin (B) is formed of a propylene-ethylene block copolymer (B-1), at least one of an ethylene elastomer and a styrene elastomer (B-2) and an inorganic filler (B-3).
