摘要： This invention relates to antistatic compositions of high molecular weight linear aliphatic polyamides which are stabilized against yellowing due to the action of heat. These polyamides which may be formed into films or fibers, are prepared by the solvent-free condensation of salts of aliphatic diamines with aliphatic dicarboxylic acids and/or lactams and contain homogeneously distributed therein a composition of one or more polyoxyalkylene compounds and tertiary amides or diamides, having at least one tertiary amide group.

摘要： A continuous process for the granulation of alcohol- and water-moist carboxymethyl cellulose (CM) produced by standard methods, wherein the CMC still moist with adhering aqueous alcohol is continuously introduced into a stirring unit, of which the length-to-diameter ratio is greater than 1 and of which the radial stirring elements are mounted on a shaft extending longitudinally in the stirring unit, and is taken up by the stirring elements, which rotate at a peripheral speed of at least 2 m/sec, being percussively size-reduced, and at the same time is brought into contact with steam flowing in countercurrent, and after a residence time of at least 1 minute, is discharged from the stirring unit and dried in the usual way.

摘要： The invention relates to antistatic polyamide compositions comprising a polyamide and as an antistatic agent from 0.1 to 20%, preferably from 1.5 to 15%, by weight based on the total weight of the composition of urethanes with ether groups. The urethanes with ether groups are stable in melts of aliphatic polyamides for prolonged periods at temperatures of up to about 300.degree. C. and filaments and fibers of such polyamides or woven fabrics, knitted fabrics, non-woven or pile fabrics produced from these filaments or fibers show outstanding antistatic properties.
