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 mmφ of 95% by weight or more, and a non-passing ratio through a mesh having a sieve opening of 2.00 mmφ 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.
