Abstract
Reduced emissions of styrene and butanal are exhibited by thermoplastic compositions comprising poly(arylene ether), a polystyrene resin, optionally rubber, and an activated carbon derived from vegetable matter. The thermoplastic compositions are particularly useful for molding automobile interior parts.
Claims18
A thermoplastic composition, comprising:
- (a) about 20 to about 80 weight percent of a poly(arylene ether);
- (b) about 5 to about 80 weight percent of a polystyrene;
- (c) about 0.1 to about 15 weight percent of a rubber material;
- and
- (d) from about 0.1 to about 10 weight percent of an activated carbon derived from vegetable matter and having a surface area of about 200 to about 2,000 m2/g;
- wherein all weight percents are based on the weight of the entire composition.

A thermoplastic resin composition, comprising the reaction product of:
- (a) about 20 to about 80 weight percent of a poly(arylene ether);
- (b) about 5 to about 80 weight percent of a polystyrene;
- (c) optionally, about 0.1 to about 15 weight percent of a rubber material;
- and
- (d) about 0.1 to about 10 weight percent of an activated carbon derived from vegetable matter and having a surface area of about 200 to about 2,000 m2/g;
- wherein all weight percents are based on the weight of the entire composition.
3 more elements
A method for making a thermoplastic composition, comprising:
- dry-blending about 20 to about 80 weight percent of a poly(arylene ether);
- about 5 to about 80 weight percent of a polystyrene;
- optionally, about 0.1 to about 15 weight percent of a rubber material;
- and about 0.1 to about 10 weight percent of an activated carbon derived from vegetable matter and having a surface area of about 200 to about 2,000 m2/g, wherein all weight percents are based on the weight of the entire composition;
- melting the dry-blended composition;
- and
- extruding the melted composition.
