    摘要： The present invention is a polyamide composition with high impact strength which is retained at low temperatures. The composition consists of from 0.5 to 95 percent by weight of at least one amine terminated polyamide. The amine terminated polyamide comprises from 3 to 97 mole percent of the polyamide acid molecules having amine groups as at least two end groups of the polyamide acid molecule. The composition further contains 3 to 99.5 percent by weight of a polyamide having at least 50 mole percent of its end groups as acid groups or capped groups. The composition further has from 2 to 50 percent, and preferably 15 to 30 percent based on the total weight of the polymer of a reactive polymer. The reactive copolymer is based on a copolymer of ethylene and an .alpha.-olefin having 3 to 8 carbon atoms. This copolymer is identified as the "ethylene copolymer". The reactive copolymer has a reactive moiety, preferably grafted to the ethylene copolymer, which is preferably an ethylenically unsaturated dicarboxylic acid or derivative thereof. There are at least an average two reactive groups per molecule of copolymer.

    摘要： The present invention is a flame retardant composition comprising from 5 to 20 weight percent of a homopolymer of a monomer having the formula: ##STR1## wherein n=0 or 1, X is bromine or chlorine and R is hydrogen or methyl. The polymer has a molecular weight between 1.times.10.sup.3 and 10.times.10.sup.6, and preferably 5.times.10.sup.3 to 5.times.10.sup.6. The molecular weight is determined by gel permeation chromatography in tetrahydrofuran. The composition contains from 80 to 95 weight percent of a polyamide. There can be from 0 to 10, preferably 1 to 10, and more preferably 2 to 6 weight percent of antimony oxide. Optionally, the composition can contain an impact modifier and/or a filler.
