    Abstract: 1. A process for the production of cellular or non-cellular polyurethane elastomers from organic polyisocyanates, relatively high molecular weight polyhydroxy compounds and chain extenders in the presence or absence of catalysts, blowing agents, auxiliaries and additives, wherein there are used as polyhydroxy compounds polyester polyols obtained by polycondensation of an organic dicarboxylic acid with an alcohol mixture consisting of 40 to 100% by weight, based on the alcohol mixture, of a diol mixture which in its turn consists essentially of (a) 10 to 30% by weight of 1,4-butanediol, (b) 40 to 60% by weight of 1,5-pentanediol, and (c) 15 to 35% by weight of 1,6-hexanediol, the percentages by weight being based on the total weight of the diol mixture, and 60 to 0% by weight, based on the alcohol mixture, of a dihydric alcohol selected from the group consisting of ethylene glycol, 1,2-propylene glycol, 1,3-propylene glycol, 1,8-octanediol, neopentyl glycol, 1,4-bis-(hydroxymethyl)cyclohexane, 2-methyl-1,3-propanediol, 3-methyl-1,5-pentanediol, diethylene glycol, dipropylene glycol and dibutylene glycol, or 90 to 98% by weight, based on the alcohol mixture, of the above diol mixture, and 2 to 10% by weight, based on the alcohol mixture, of a trihydric and/or tetrahydric alcohol.

The compound having an ethylenically unsaturated group (h) is used in amounts corresponding to 0.02-0.08 gram equivalent, based on the polyisocyanate (a), of OH, and the polyurethane, dissolved in dimethylformamide, has a Fikentscher K value greater than 40 or is insoluble in dimethylformamide.
