Abstract

1,144,233. Polyurethanes. MOBAY CHEMICAL CO. 3 Oct., 1966 [15 Oct., 1965], No. 44087/66. Heading C3R. A blend suitable for the production of spandex fibres by extrusion comprises a mixture obtained by mechanical means of (1) a linear polyurethane prepared by reacting a polymeric diol having M.W. at least 500, a glycol having M.W. < 300 with an organic diisocyanate in an NCO: OH ratio of 0À95 to 1À02, and (2) from 1 to 10% by wt. based on (1) of a blocked polyisocyanate. The latter may have a functionality of 2 to 4, e.g. the reaction product of 3 moles of 2,4-tolylene diisocyanate with 1 mole of trimethylolpropane.
