Abstract

1339813 Melt-spinnable polyurethane elastomers MONSANTO CO 5 Nov 1971 51611/71 Heading C3R [Also in Division B5] Melt-spinnable fibre-forming polyurethane elastomers prepared by reacting a polymeric glycol of M.W. between 800 and 3000, a polyisocyanate and sufficient of a chain extending agent to give an NCO/OH ratio of 0À98 to 1À06 contain as a non-sticking additive a compound having any of the following formulµ wherein R 1 and R 2 are the same or different radicals selected from a C 1-24 aliphatic radical with 0 to 3 double bonds between the carbon atoms, an alicyclic radical and an aromatic radical, X 1 and X 2 are the same or different radicals selected from carbonyl and sulphonyl radicals, Y is an organic divalent radical and the total number of CH 2 groups in the R 1 , R 2 and Y radicals is at least 9. The polyurethane may be formed in the presence of the additive or the polyurethane is preformed and the additive added thereto. The additive preferably melts in the range of 120‹ to 240‹ C. and may be, for example, methylene bis-(stearamide), ethylene bis - (stearamide), distearyl 4.4<SP>1</SP>- methylene - bis - (phenylcarbamate), 4,4<SP>1</SP>- distearylureidodiphenylmethane, ethylene bis- (hexadecylsulphonamide) or ethylene bis- (oleamide).
