Abstract

Linear segmentedpolyurethane elastomers containing a chain extending segment of the formula wherein X is 1 or 2 may be prepared by reacting an NCO-terminated prepolymer suitably derived from a dihydroxy compound having a M.W. of 600 to 5000 and excess of an organic diisocyanate with a substantially equivalent quantity of an aliphatic semicarbazide hydrazide of the formula wherein x is 1 or 2 in the presence of a highly polar solvent. The prepolymer may suitably be prepared in the further presence of a diol having a M.W. of 62 to 300, which diol preferably contains tertiary amino groups in the molecule. Up to 45 mol. per cent of the aliphatic semicarbazide hydrazide may be replaced by a conventional bifunctional chain extender. Preferred solvents are those containing amide, urea or sulphoxide groups. The elastomer containing solutions may be spun into filaments. In a typical example (1) a polyester derived from adipic acid, 1,6-hexane diol and 2.2-dimethyl propane diol is heated with N,N-bis-(#-hydroxy propyl)- methylamine and diphenylmethane-4,41-diisocyanate in chlorobenzene to form an NCO- terminated prepolymer which is then reacted with a solution of #-semicarbazide propionic acid hydrazide in dimethyl formamide. The viscosity of the elastomer solution is increased by the addition of a further quantity of the NCO- terminated prepolymer, and after pigmenting with TiO 2 the solution is spun to form filaments.
