A process for the manufacture of rubber-elastic polymers configurable from the solution containing urethane groups by reaction of polyhydroxidized compounds, having at least two terminal isocyanate groups, with bifunctional cross-linking and chain-lengthening agents, according to isocyanate polyaddition process, characterized in that for the regulation of the reaction rate, 0.002-2.0, especially 0.01 to 0.7 moles, of ammonia are added per mole of the chain elongation or crosslinking agent.
