Abstract
A graft copolymer comprises a substrate of a diene rubber, and a homogeneous superstrate containing units of acrylonitrile and at least one aromatic olefin having a molar ratio of acrylonitrile to olefin between 2 and 9. The superstrate may also contain a minor amount (preferably less than 10 mole %) of at least one other comonomer selected from acenaphthylene, vinyl carbazole and its derivatives, maleimide and its N-substituted derivatives and norbornene and its derivatives.
