Abstract: A PROCESS IS PROVIDED FOR THE PRODUCTION OF POLYURETHANE ELASTOMERS BY REACTING HIGHER MOLECULAR WEIGHT HYDROXY COMPOUNDS WHICH HAVE A MOLECULAR WEIGHT OF 800 TO 2500, DIISOCYANATES AND LOW MOLECULAR WEIGHT COMPOUNDS WHICH HAVE A MOLECULAR WEIGHT OF UP TO 400 AND WHICH CONTAIN AT LEAST TWO HYDROGEN ATOMS REACTIVE WITH ISOCYANATES, CHARACTERIZED IN THAT THE HIGHER MOLECULAR WEIGHT HYDROXY COMPOUNDS ARE CONDENSATION PRODUCTS OF 1,6-HEXANE DIOL, ADIPIC ACID AND DIARYL CARBONATE.
