Polyurethane rubber compositions with good resistance to heat, light, and discoloration by gases were contained 1,3,5-tris (4-tert-butyl-3-hydroxy- 2,6 -dimethylbenzyl)isocyanuric acid(I) or similar derivatives and UV absorbers. Thus, a solution of polytetramethylether glycol- 1,2 -propylenediamine-4,4'-diphenylmethanediisocyanate copolymer 100, I. 0.32 parts were used to prep. 40 denier fiber.
