    摘要: 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.

    摘要: New Ionomer compositions which have improved moldability and improved high temperature behavior are based on ionomer polymerized at normal pressures but lower than normal temperatures. The compositions may be blends with standard ionomer, particularly if the low-temperature-prepared ionomer is prepared at very low temperatures which reduces productivity compared with standard ionomer, or useful alone when prepared at intermediate temperatures.
