Abstract:
1. A method for producing a polyolefin-based resin molded article, comprising a step of molding a molten polyolefin-based resin composition in which crystals of an amide compound represented by the following general formula (1) are present in a polyolefin-based resin in a molten state, wherein the molten polyolefin-based resin composition contains a phenol compound, and a blending ratio of the amide compound and the phenol compound is 60:40 to 10:90 (weight ratio), wherein n represents an integer of 2 to 4, R wherein the phenol compound is n-octadecyl-β-(4′-hydroxy-3′,5′-di-tert-butylphenyl)propionate, 2,4-bis(octylthiomethyl)-6-methylphenol, a compound represented by general formula (2b): wherein p represents an integer of 1 to 4, p R 3 s are the same or different and each represent a linear or branched alkyl group having 1 to 25 carbon atoms that may have an ester bond, a thioether bond, or an ether bond, and X represents a linear or branched alkylene group having 1 to 10 carbon atoms that may have an ester bond or an ether bond, or a compound represented by general formula (2c): wherein q represents an integer of 1 to 4, q R 3 s are the same or different and each represent a linear or branched alkyl group having 1 to 25 carbon atoms that may have an ester bond, a thioether bond, or an ether bond, and Y represents a linear or branched alkylene group having 1 to 10 carbon atoms, and wherein a blending amount of the phenol compound is 0.07 to 1 parts by weight per 100 parts by weight of the polyolefin-based resin.
