High-impact polyamide molding and extrusion resin compositions

DETAILED DESCRIPTION What is claimed is: 1.
The product of the process of melt blending: (a) from about 50 to about 97% by weight of a polyamide resin derived from (1) the reaction of a dicarboxylic acid or derivative thereof containing from two to twenty carbon atoms with a diamine containing from two to fifteen carbon atoms, or (2) the polymerization of a lactam, and (b) from about 3 to about 50% by weight of an elastomer which (1) contains from about 5 to about 500 mole equivalents of polyamide reactive chlorine or bromine atoms per 10.
sup.
6 grams of elastomer, said chlorine or bromine atoms being present in the elastomer in segments of the formula: ##STR3## wherein, X is (i) a monovalent radical selected from the group consisting of phenyl, vinyl, carboxy, cyano and nitro, or (ii) a divalent radical selected from the group consisting of oxy, carbonyl, thio, sulfone and corresponding divalent radicals of said (i) radicals; R is hydrogen or alkyl when X is an (ii) radical, and a divalent radical when X is an (i) radical; and Halo is the chlorine or bromine; and (2) has a glass transition temperature of less than 0.
degree.
C.
2.
The product of claim 1 wherein the polyamide resin is selected from the group consisting of polyhexamethylene adipamide, polyhexamethylene azealamide, polyhexamethylene sebacamide, polycaprolactam, polyhexamethylene isophthalamide, polyhexamethylene tere-co-isophthalamide and mixtures and copolymers of the above.
3.
The product of claim 1 or 2 wherein the elastomer is selected from the group consisting of halogen functional poly(ethylene/propylene), polybutadiene, poly(styrene/butadiene), poly(ethylene/propylene/diene), poly(acrylonitrile/butadiene), polyacrylate, poly(ethylene/acrylate), poly(propylene/acrylate), polyisobutylene, polyisoprene, poly(isobutylene/isoprene), poly(ethylene/vinyl acetate) elastomers, and mixtures thereof.
4.
The product of claim 1 wherein the amount of polyamide resin blended is 70-95% by weight and the amount of elastomer blended is 5-30% by weight
