    Abstract: Molding mass comprises a polyamine-polyamide graft copolymer and a thermoplastic polyester. The graft copolymer is prepared from a branched polyamine and, as polyamide-forming monomers, lactams, omega -aminocarboxylic acids and/or equimolar amounts of diamines and dicarboxylic acids. Molding mass (A) comprises 0.1-5 weight parts of a polyamine-polyamide graft copolymer (I) and 95-99.9 weight parts thermoplastic polyester (II). (I) is prepared from 0.5-25 wt.% of a branched polyamine with at least 4 nitrogen atoms and number average molecular weight at least 146, and, as polyamide-forming monomers, lactams, omega-aminocarboxylic acids and/or equimolar amounts of diamines and dicarboxylic acids. Independent claims are also included for the following: (1) mass (A') for injection molding comprising 0.1-20 weight parts (I) and 80-99.9 weight parts (II); (2) molding mass (A'') containing (i) 40-99.5wt.% mixture as defined for (A') and (ii) the balance particulate, lamellar and/or fibrous fillers, pigments, reinforcing agents, additives, agents that impart anti-electrostatic or electrical conduction properties, nucleating agents and particulate flame-proofing agents; and (3) molded articles prepared from (A)-(A'').
