This invention relates to a process for the production of light resistant and exhaust gas resistant PUH elastomer threads and films based on segmented polyurethane ureas which are based on diisocyanate mixtures of from 30 to 85 mol% of trans-1,4-cyclohexylene diisocyanate and from 70 to 15 mol% of other aliphatic or cycloaliphatic diisocyanates. The diisocyanates are first reacted with relatively high molecular weight dihydroxy compounds and optionally low molecular weight diols to form an isocyanate prepolymer which is then reacted with aliphatic diamines or diamine mixtures, preferably ethylene diamine, in highly polar solvents, optionally in the presence of salt type solubilizing agents such as lithium salts and preferably with the aid of aliphatic chain terminators, in particular those having a cycloaliphatic structure, to produce elastomer solutions which are stable under processing conditions. These solutions are spun in the conventional manner or dried to form films or coagulated to form sheet products. The invention also relates to the segmented polyurethane urea elastomers, in particular threads, obtainable by the new process.
