ABSTRACT OF THE DISCLOSURE Segmented elastomeric polyester polyurethane-urea spandex filaments having improved resistance to degradation by ultraviolet radiation and chlorine-containing bleaches in which the hard segments contain ureylene groups joined to functionally non-aromatic radicals, at least 25 mole percent of which are or are provided as well as a process for preparing them from a polymer formed from a polyester glycol, a func-tionally non-aromatic diisocyanate and a functionally non-aromatic diamine. A sufficient amount of the diiso-cyanate and/or diamine having the structure or wherein R is -NCO or -NH2 is reacted to provide at least 25 mole percent of the sum of the diisocyanate and diamine residues in the hard segment with the structure or |
