This invention relates to a process for standardized preparation of thermoplastic polyurethane elastomers by deactivating metal traces during the reaction, at an NCO: OH ratio of between about 0.85 and about 1.2:1, of (a) substantially linear hydroxyl-terminated polyols; (b) organic diisocyanates; (...
