Polyblends of thermoplastic polynorbornene nitrile polymers, styrenemaleic anhydride polymers and acrylonitrile-butradiene-styrene polymers

摘要

Molding compositions are prepared from blends of (A) thermoplastic polynorbornene nitrile polymers; (B) styrene/maleic anhydride polymers; (C) at least one of the polymers selected from the group consisting of ABS polymers, MBS polymers, and styrene/acrylonitrile polymers. Component B, the styrene/maleic anhydride polymer may optionally contain a termonomer such as methylmethacrylate or acrylonitrile and a rubber component.
