Abstract
Novel compositions are disclosed which include a polyphenylene ether resin and an alkenyl aromatic resin modified with a polysiloxane in the form of small rubber-like particles. Also included within the scope of this invention are reinforced and flame-retardant compositions of the polyphenylene ether resin and the alkenyl aromatic resin modified with a polysiloxane.
Claims23
A thermoplastic molding composition which, after molding, has good impact resistance, said composition comprising:
- (a) a polyphenylene ether resin;
- and
- (b) an alkenyl aromatic resin that is modified with a polysiloxane in the form of small rubber-like particles by polymerizing alkenyl aromatic monomer in the presence of the polysiloxane.
A thermoplastic molding composition which, after molding has good impact strength, said composition comprising:
- (a) from 10 to 95% by weight of a polyphenylene ether resin;
- and
- (b) from 90 to 5% by weight of an alkenyl aromatic resin that is modified with a polysiloxane in the form of small rubber-like particles by polymerizing alkenyl aromatic monomer in the presence of the polysiloxane.
