Abstract

Disclosed is an additive for a thermoplastic resin, which provides a thermoplastic resin composition excellent in formability and also provides a shaped article excellent in surface appearance and flame retardance. The additive for a thermoplastic resin comprises tetrafluoroethylene polymer (A) and alkyl methacrylate polymer (B) containing 50% by mass or more of units of alkyl methacrylate having an alkyl group with carbon numbers of 2 to 6.

Claims (10)

1. A thermoplastic resin composition comprising:

a thermoplastic resin and

an additive for the thermoplastic resin, wherein the additive comprises tetrafluoroethylene polymer (A) and alkyl methacrylate polymer (B) containing 50% by mass or more of units of i-butyl methacrylate.

2. The thermoplastic resin composition according to claim 1 , wherein the thermoplastic resin is a polyolefin resin.

3. The thermoplastic resin composition according to claim 1 ,

further comprising a flame retardant.

4. The thermoplastic resin composition according to claim 1 , further comprising a phosphate salt flame retardant.

5. An article produced by shaping the thermoplastic resin composition according to claim 1 .

6. An article produced by shaping the thermoplastic resin composition of claim 1 by extrusion molding, injection molding, calendaring, blow molding, thermoforming, foaming, vacuum forming or melt spinning.

7. An article produced by shaping the thermoplastic resin composition of claim 1 selected from the group consisting of a sheet, film, material for a household appliance, automotive material, and covering material for an electric wire.
