Abstract
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).
Claims11
A thermoplastic resin composition comprising a thermoplastic resin (A), an acrylic polymer (B), a polytetrafluoroethylene-containing powder mixture (C) and a filler (D), an amount of the acrylic polymer (B) being from 0.1 to 18 parts by weight, an amount of the filler (D) being from 1 to 2000 parts by weight, based on 100 parts by weight of the thermoplastic resin (A), wherein
- an amount of a polytetrafluoroethylene component in the polytetrafluoroethylene-containing powder mixture (C) is from 0.1 to 18 parts by weight based on 100 parts by weight of the thermoplastic resin (A), and
- wherein the acrylic polymer (B) comprises an acrylic monomer (b-1) containing an alkyl methacrylate and/or an alkyl acrylate, an alkyl group of which has 1 to 18 carbon atoms, and a reduced viscosity (η sp/C) at 25° C. of a solution prepared by dissolving 0.1 g of the acrylic polymer in 100 ml of chloroform is 15 or less.
A method of improving moldability of a thermoplastic resin composition comprising 100 parts by weight of a thermoplastic resin (A), 0.1 to 18 parts by weight of an acrylic polymer (B), a polytetrafluoroethylene-containing powder mixture (C) and 1 to 2000 parts by weight of a filler (D), which comprises the step of:
- adding the polytetrafluoroethylene-containing powder mixture (C) so that an amount of a polytetrafluoroethylene component in the polytetrafluoroethylene-containing powder mixture (C) is from 0.1 to 18 parts by weight based on 100 parts by weight of the thermoplastic resin (A), and
- wherein the acrylic polymer (B) comprises an acrylic monomer (b-1) containing an alkyl methacrylate and/or an alkyl acrylate, an alkyl group of which has 1 to 18 carbon atoms, and a reduced viscosity (η sp/C) at 25° C. of a solution prepared by dissolving 0.1 g of the acrylic polymer in 100 ml of chloroform is 15 or less.
