  • Patent number: 6399684
    Abstract: 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.

  • Patent number: 5866658
    Abstract: Blends of highly-neutralized ionomers of copolymers of ethylene and high weight percentages of .alpha.,.beta.-ethylenically-unsaturated C.sub.3 -C.sub.8 carboxylic acids dispersed in a continuous or co-continuous polyamide phase are provided and a process for making such blends. The blends are particularly useful in applications such as molded parts where toughness, high gloss, abrasion/scratch (mar) resistance, UV resistance, high temperature properties and stiffness are desired.
