ABSTRACT OF THE DISCLOSURE The present invention relates to new polyether urethanes correspond- ing to the general formula Image in which R' and R" independently of one another represent a member selected from the group consisting of a straight-chain, cyclic or branched, saturated or unsaturated aliphatic hydrocarbon radical, a straight-chain, cyclic or branched, saturated or unsaturated aliphatic hydrocarbon radical containing hetero atoms, an aralkyl radical, an aromatic radical and an alkyl-substit- uted aromatic radical, at least one of the two radicals R' and R" comprising an alkyl radical with from 10 to 30 carbon atoms, R'" represents a member selected from the group consisting of hydrogen atom, an alkyl group with from 1 to 5 carbon atoms, a cycloalkyl, an arylalkyl and an aralkyl group, and n is a number of at least 3, preferably from 7 to 45 and to a process for their production. The polyether urethanes are stable for prolonged per- iods at temperatures of up to approximately 300C in a;iphatic polyamide melts, and polyamides containing urethanes of this kind, more especially filaments and fibres of such polyamides or woven fabrics, knitted fabrics, nonwovens or pile fabrics produced from these filaments or fibres, show ex- cellent antistatic properties.
