  • Thermoplastic polyetheramide/styrene copolymer compositions
    Patent number: 5496876
    Abstract: Improved thermoplastic compositions adopted for easy conversion, e.g., by injection molding or extrusion techniques, into useful shaped articles having high flexibility, and good tear resistance and elasticity, include a polyetheramide, advantageously a polyetheresteramide, and a styrene/diene copolymer, e.g., a copolymer of styrene with butadiene or isoprene, notably a linear or branched chain styrene/butadiene/styrene or styrene/isoprene/styrene copolymer.
    Type: Grant
    Filed: September 28, 1994

  • Elastomeric polyetheramide/nitrile rubber compositions
    Patent number: 4866127
    Abstract: Improved thermoplastic elastomeric compositions adopted for easy conversion, e.g., by injection molding or extrusion techniques, into useful shaped articles having good abrasion and tear resistance, and marked resistance to oils and fats, include a polyetheramide, advantageously a polyetheresteramide, and a nitrile rubber, e.g., a copolymer of 1,3-butadiene or isoprene with (meth)acrylonitrile.
