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.
Claims15
A thermoplastic polymeric composition of matter, comprising a polyetheramide and a styrene/diene copolymer, wherein the polyetheramide is the predominant component of the polymeric composition relative to the styrene/diene copolymer, and wherein said polyetheramide comprises a copolycondensation block polymerizate of a polyamide having terminal amino groups at each end of the polyamide, with a polyoxyalkylene polyether having terminal carboxylic acid groups at each end of the polyether.
A thermoplastic polymeric composition of matter, comprising a polyetheramide and a styrene/diene copolymer, wherein the polyetheramide is the predominant component of the polymeric composition relative to the styrene/diene copolymer, and wherein said polyetheramide comprises a copolycondensation block polymerizate of a polyamide having terminal carboxylic acid groups at each end of the polyamide with a polyoxyalkylene polyether having terminal amino groups at each of the polyether.
A thermoplastic polymeric composition of matter, comprising a polyetheramide and a styrene/diene copolymer, wherein the polyetheramide is the predominant component of the polymeric composition relative to the styrene/diene copolymer, and wherein said polyetheramide comprises a copolycondensation block polymerizate of a polyamide having terminal amino groups at each end of the polyamide, with a polyoxyalkylene polyether having terminal carboxylic acid groups at each end of the polyether, or wherein said polyetheramide comprises a copolycondensation block polymerizate of a polyamide having terminal carboxylic acid groups at each end of the polyamide, with a polyoxyalkylene polyether having terminal amino groups at each end of the polyether, and wherein said styrene/diene copolymer comprises a linear or branched chain styrene/butadiene/styrene or styrene/isoprene/styrene polymer.
