ANTISTATIC POLYAMIDE COMPOSITIONS, THEIR USE AND PROCESSES FOR THEIR PRODUCTION

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, which do not contain free hydroxyl groups and which do not have any hydrogen atoms on the nitrogen atom. These 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 poly-amides or woven fabrics, knitted fabrics, non-woven or pile fabrics produced from these filaments or fibers show outstanding antistatic properties.
