ABSTRACT:
An impact resistant nitrogeneous polymer comprises a multiphase amine-reactive moiety-containing polymer grafted to a polycarbonamide containing recurring amide linkages as an integral part of the polymer chain; the grafting, by reaction of an amine-reactive moiety of the polymer with an amine end group of the polycarbonamide. Preferably the amine-reactive moiety-containing polymer is a multiphase carboxylic acid-containing polymer comprising (A) a first elastomer phase that is preferably polymerized from monomers comprising; 50 to 99.9 parts by weight alkyl acrylate wherein the alkyl group contains 1 to 15 carbon atoms, butadiene or substituted butadiene; 0 to 40 parts by weight of other ethylenically unsaturated monomers; 0 to 5 parts by weight of a polyethylenically unsaturated crosslinking monomer; and 0 to 5 parts by weight of a graft-linking monomer; and (B) a final rigid thermoplastic stage containing amine-reactive carboxylic acid groups and polymerized from monomers comprising; 1 to 50 parts by weight of a copolymerizable carboxylic acid; 50 to 99 parts by weight of a member selected from the group consisting of alkyl methacrylates, styrenes, acrylonitrile, methacrylonitrile and olefins that, when homopolymerized, form polymers having a heat distortion temperature greater than about 20.degree. C; 0 to 49 parts by weight of another acrylic monomer; and 0 to 40 parts of another copolymerizable ethylenically unsaturated monomer. The impact resistant nitrogenous polymer is characterized by superior hot strength that renders the polymer extrudable, blow moldable, and injection moldable.
