摘要： The present invention relates to new polyether urethanes corresponding to the general formula ##STR1## and to a process for their production. The polyether urethanes are stable for prolonged periods at temperatures of up to approximately 300.degree. C in aliphatic polyamide melts, and polyamides containing urethanes of this kind, more especially filaments and fibers of such polyamides or woven fabrics, knitted fabrics, nonwovens or pile fabrics produced from these filaments or fibers, show excellent antistatic properties.

摘要： High molecular weight aromatic copolyamides which contain a small proportion of structural units having 2,3-(1H,3H)-quinazoline dione rings are disclosed. The presence of quinazolinedione ring units in the copolyamide results in an increased moisture absorption capacity. By using small amounts of quinazoline dione units, the good physical properties of the corresponding quinazoline dione-free polyamide are substantially retained while the moisture absorption is significantly increased. Larger amounts of quinazoline dione units than contemplated (15 mol percent and more) do not improve the moisture absorption further and adversely affect the physical properties. The copolyamides are useful in textile applications in which the improved moisture absorption serves to make clothing prepared from such textiles more comfortable.
