Abstract: The present invention provides a process for producing a thermoplastic resin composition comprising a polyolefin wax having good dispersibility for a thermoplastic resin, a molded product, which is excellent in physical properties such as blocking property and mechanical properties, from the thermoplastic resin composition and a process for producing the molded product. Specifically, a process for producing a thermoplastic resin composition comprises melt-kneading a mixture of a polyolefin wax (A) which has a passing ratio through a mesh having a sieve opening of 5.66 mm? of 95% by weight or more, and a non-passing ratio through a mesh having a sieve opening of 2.00 mm? of 95% by weight or more, and is in the particle form, and a thermoplastic resin (B), a molded product, which is excellent in physical properties such as blocking property and mechanical properties, obtained from the thermoplastic resin composition and a process for producing the molded product are provided.

Abstract: The present invention provides a process for producing a thermoplastic resin composition having good dispersibility of a polyolefin wax for a thermoplastic resin under a stable production condition, a process for producing a molded product using the thermoplastic resin composition, and a molded product obtained from the thermoplastic resin composition. According to the present invention, a mixture of a wax masterbatch (A) containing a polyolefin wax and a thermoplastic resin, and a thermoplastic resin (B) is melt-kneaded to prepare the thermoplastic resin composition and the molded product.

Abstract: The present invention provides an injection molding process of a thermoplastic resin which is capable of preventing the burning of the resin and reducing the cooling time after injection. The process for producing an injection molded product comprises injection molding a mixture containing a thermoplastic resin and a polyolefin wax at a molding temperature lower than that of the mixture excluding the polyolefin wax by at least 5° C.

Abstract: The present invention provides an injection molding process of a thermoplastic resin which is capable of thin molding or precision molding by improving injection moldability, particularly releasability or fluidity, without deteriorating the characteristics of the injection molded article of the thermoplastic resin. The process for producing an injection molded product comprises injection molding a mixture containing a thermoplastic resin and a polyolefin wax, wherein the mixture has L/L0?1.05, the L being a flow length in the case where the mixture contains the polyolefin wax and the Lo being a flow length in the case where the mixture contains no polyolefin wax, the L and L0 being measured under the conditions of a mold temperature of 40° C. and a resin temperature, Tr, as determined by the following equation: Tr=¾×Tm+100 (wherein Tm represents a melting temperature (° C.) of the thermoplastic resin), using a spiral flow mold having a thickness of 1 mm and a width of 10 mm.
