Abstract

The present invention relates to polyamide/polymer blends having a morpholog y enhancing reagent selected from a phosphorous containing compound such as a hypophosphite salt. Significant physical effects are seen in Tensile strengt h as well as Vicat softening points. The blends having polyamide and a polymer selected from, for example, a neutralized ethylene copolymer, and the phosphorous containing reagent are useful in producing molded parts and othe r fabricated parts requiring high strength and toughness. Molded parts produce d from such blends also have high gloss, high abrasion/scratch resistance and good high temperature properties.
