Patent number: 6399684Abstract: The present invention relates to polyamide/polymer blends having a morphology enhancing reagent selected from a phosphorous containing compound such as a hypophosphite salt. Significant physical effects are seen in Tensile strength 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 other fabricated parts requiring high strength and toughness. Molded parts produced from such blends also have high gloss, high abrasion/scratch resistance and good high temperature properties.Type: GrantFiled: August 19, 1999Date of Patent: June 4, 2002Assignee: E. I. du Pont de Nemours & CompanyInventor: Charles John Talkowski
