Notes:
Physical and mechanical properties of alpha-methylstyrene-methacrylonitrile copolymer have been determined. The effects of copolymer composition and inherent viscosity (molecular weight) on deflection temperature under load, Izod impact strength, tensile, and flexural properties are reported. The azeotropic copolymer of 57 mole-% methacrylonitrile possessed the best overall properties with a DTUL of 129°C and an Izod impact strength of 0.3 ft-lb/in. notch. The impact strength of the copolymer was improved by graft copolymerization upon a butadiene-methacrylonitrile copolymer. The impact-modified copolymer possessed an Izod impact strength of 6 ft-lb/in. notch and a DTUL of 115°C.
