摘要: An improved process for the manufacture of polyurethane elastomers from a reaction mixture which comprises a polyol, an isocyanate, water, a bismuth catalyst and an optional filler. In the improved process of this invention, the rate of reaction is decreased by the addition of water to the reaction mixture and increased by the removal of water from the reaction mixture.
