ABSTRACT:
Thermoplastically workable polyurethane-elastomers are disclosed which are obtained through polyaddition of substantially pure trans-cyclohexane-1,4-diisocyanate, macrodiols of average molecular weight from 800 to 4000 and bisethoxylated Bisphenol A or mixtures thereof with short-chain diols customarily employed as chain lengtheners. The polyurethanes possess the advantage that their softening points lie in a very favorable temperature range which makes possible their thermoplastic workability at below the decomposition temperature, and also guarantees outstanding mechanical-elastic characteristics as well as excellent long-term light stability. As a result the polyurethanes according to the present invention are outstandingly suitable as material for shaped bodies to be employed in areas of use placing high requirements on the employed materials. For example, highly valuable elastomer fibers can be manufactured from these polyurethanes by means of melt spinning.
