Abstract
Elastomeric polyurethanes, e.g. as prepared by reacting diisocyanate-capped, essentially linear polyester or polyether and polyol suitable for cross-linking thereof, are inhibited against undesired hardening in use or storage by including in the polyurethane-forming reactant mixture a plasticizing composition composed of carboxylate having a 200-1,000 molecular weight and at least two monocyclic aryl radicals per molecule and, based on the weight of said carboxylate, 0.1-5% glycol having a 62-500 molecular weight.
