Abstract:
The present invention is a composition useful as an impact modifier for polyamide compositions. In one embodiment, impact modifiers of the present invention are ethylene maleic anhydride copolymers having at least 3% maleic anhydride functionality. Compositions comprising copolymers of ethylene and maleic anhydride or its functional equivalents and ethylene copolymers with polar comonomers are disclosed. The compositions provide miscible blends and exhibit improved properties, such as increased temperature resistance and mechanical strength, compared to pure ethylene copolymers with polar comonomers.
