Orientated gel molding method of polyolefin-based resin composition and molded article obtainable by the method |
摘要 |
The present invention provides a method of molding a polyolefin-based resin comprising the steps of dissolving at least one dibenzylidene sorbitol compound in a molten polyolefin resin, cooling the molten resin to a temperature not higher than the sol-gel transition temperature during the cooling cycle to form network-like crystals of the dibenzylidene sorbitol compound, and molding the resulting resin composition at a temperature not lower than the melting temperature of the polyolefin-based resin but not higher than the sol-gel transition temperature during the heating cycle; and a polyolefin resin molded article obtainable by this molding method.
