    摘要： The invention relates to polyamide compositions of high-molecular weight, linear aliphatic polyamides with reduced surface resistance which are produced by solvent-free condensation of salts of aliphatic diamines and aliphatic dicarboxylic acids and/or of lactams and in which polyester amides which have been obtained by condensation of dicarboxylic acids or their derivatives, diols and primary-secondary aliphatic diamines are homogeneously distributed.

    摘要： The invention relates to a process for the production of filaments and fibres having a moisture absorption of at least 7% and a water retention capacity of at least 25% by dry-spinning an acrylonitrile copolymer, containing more than 50 mval of carboxyl groups from a solvent, which contains 5 to 50% by weight of a compound with properties defined herein, washing the compound added to the solvent out of the freshly spun filaments and fibres and partly or completely converting the carboxyl groups into the salt form. The invention further relates to dry-spun filaments and fibres having a core and sheath structure, comprising a fibre-forming acrylonitrile copolymer having more than 50 mval of carboxyl and carboxylate groups and having a moisture absorption capacity of at least 7% and a water retention capacity of at least 25%.

    摘要： The invention is related to novel polycaprolactam filaments and fibres capable of being deeply dyed with acid dyes to give dye finishes with extreme fastness to light, characterized by the fact that they consist of physical mixtures of unmodified polycaprolactam and a basic polycaprolactam containing structural units corresponding to the formula: ##STR1## in which R represents an alkylene radical with 4 to 12 carbon atoms and x is an integer from 1 to 5, have relative solution viscosities of from 2.9 to 3.5 (as measured on solutions of 1 g of non-extracted polyamide in 100 ml of cresol at 25.degree. C) and contain free amino groups in a concentration range from 60 to 180 millivals per kg of polymer mixture.

    摘要： The invention relates to a composition of matter which comprises A) from 95 to 99.9 % by weight of a copolymer of acrylonitrile, a vinyl and/or vinylidene halide and, optionally, at least one other copolymerisable compound; and B) from 0.1 to 5 % by weight of a substantially water-insoluble complex antimony compound containing amide groups, the complex antimony compound being obtainable by esterifying an .alpha.-hydroxy polycarboxylic acid with a polyol, reacting the esterification product with an antimony oxide in a polar organic solvent adding a monoisocyanate to the resulting solution in such a quantity that the free carboxyl groups are converted into the corresponding amide groups, and a process for the production of these compositions of matter.
