OXIDIZED POLYPROPYLENE AND IONOMERS THEREOF AS COMPATIBILIZERS FOR POLYPROPYLENE/NYLON-6 BLENDS

摘要

Oxidized polypropylene and ionomers thereof were evaluated as compatiblizers for polypropylene/ nylon-6 (PP/PA-6) blends. For these blends, the ionomer of oxidized PP provided better morphology and physical properties than the oxidized PP. The change in morphology was also reflected in the rheological behaviors that the compatibilized blends showed an increase in melt elasticity. With improvement in flowability and yellowing resistance, the ionomer of oxidized PP also, for the most part, yielded mechanical properties comparable to commercially available maleated PP.
