Abstract
A novel polyether polyurethane polymer comprising the reaction product of an organic diisocyanate and a linear polyhydroxyl polyether having a molecular weight of less than 8000 and from 0.01 to 1%, by weight, of finely-divided inorganic particles is described, together with a process for producing a cast elastomer by reacting this polymer with a cross-linking or chain-extending agent.
