Polyblends comprising about 10 to about 90% by weight of polyphenylene oxide and about 90 to about 10% of SAN or ABS polymer comprising 8 to 17 average % by weight acrylonitrile in which the acrylonitrile compositional distribution in the SAN or ABS polymer is broad in that the standard deviation of the weight % AN about the mean value is at least about 3.5%.

Polyblends of polyphenylene oxide and styrene-acrylonitrile polymers

Polyblends of N-phenyl maleimide copolymers and SAN copolymers within certain imide and acrylonitrile content ranges are found to have unique compatibility properties not displayed by related copolymer blends.

Polyblends comprising N-phenylmaleimide copolymers and SAN copolymers

Polyphenylene oxide blended with SAN or ABS polymers containing from 2 to 8% by weight of acrylonitrile have highly advantageous combination of strength and distortion temperature.

Low acrylonitrile content styrene-acrylonitrile polymers blended with

Rubber-modified terpolymers of a monoalkenyl aromatic monomer, an unsaturated dicarboxylic acid anhydride and an alkyl methacrylate are found to possess an unexpectedly high heat distortion temperature over a certain range of composition.

Rubber modified terpolymers with improved heat distortion resistance

Terpolymers of a monoalkenyl aromatic monomer, an unsaturated dicarboxylic acid anhydride and an alkyl methacrylate are found to possess an unexpectedly high heat distortion temperature over a certain range of composition.

Terpolymers with improved heat distortion resistance

Rubber-modified terpolymers of from 50 to 83% of a monoalkenyl aromatic monomer, from 15 to 30% of an unsaturated dicarboxylic acid anhydride, from 2 to 20% of an unsaturated nitrile are described which are useful as molding compositions.

Rubber-modified terpolymer with improved molding characteristics

Polyblends are disclosed which comprise an ABS polymer blended with a rubber-modified polymer of a monoalkenyl aromatic monomer and an unsaturated dicarboxylic acid anhydride.
