Disclosed are a powdery processing aid for polyolefin resins, containing an alkyl methacrylate polymer which has alkyl methacrylate units having an alkyl group with 2 to 6 carbon atoms as a main component and has a mass average molecular weight of 150,000 to 20,000,000, having good handling properties as a powder, having good dispersibility in polyolefin resins, and being able to improve shaping processability of polyolefin resins; and a polyolefin resin composition having improved shaping processability, which contains a powdery processing aid for polyolefin resins and a polyolefin resin.

Powdery processing aid for polyolefin resins, method for producing the same, resin composition and shaped article

A thermoplastic resin composition comprising a polylactic acid polymer (A), an acrylic polymer (B) containing units of methyl methacrylate monomer, and a graft copolymer (C) obtained by graft-polymerizing a vinyl monomer onto a rubbery polymer, wherein the refractive index, Rc, of the graft copolymer (C) and the total refractive index, Rab, of the polylactic acid polymer (A) and the acrylic polymer (B) satisfy the following formula (1)&#x2212;0.004&#x2266;&#x2266;+0.008&#x2003;&#x2003;(1).

Thermoplastic resin composition and molded article comprising the same

The present invention provides a thermoplastic resin composition comprising a thermoplastic resin (A), an acrylic polymer (B), a polytetrafluoroethylene-containing powder mixture (C) and a filler (D), the amount of the acrylic polymer (B) being from 0.1 to 400 parts by weight, the amount of the filler (D) being from 1 to 2000 parts by weight, based on 100 parts by weight of the thermoplastic resin (A), and the amount of a polytetrafluoroethylene component in the polytetrafluoroethylene-containing powder mixture (C) is from 0.01 to 400 parts by weight based on 100 parts by weight of the thermoplastic resin (A).
