摘要： A stable dispersion of a polymer in a polyol is prepared by reacting an organic polyisocyanate with a short-chain polyol in a high molecular weight polyol containing a relatively high primary hydroxyl group content, the ratio of the content of primary hydroxyl groups in the short-chain polyol to that in the high molecular weight polyol being at least a critical lower limit of about 3.5. The reaction is further carried out in the presence of a small proportion of water to achieve a reduction in the viscosity of the resulting dispersion. The dispersion is used in preparing high resilience polyurethane foam having desirable physical properties and which is of utility in a wide variety of cushioning applications.

摘要： Isocyanate-reactive compounds are prepared by the reaction of TDI distillation residue with a polyol in such proportions as to obtain a reaction product having an OH-number (mg KOH/g) of about 200 to about 700. The TDI distillation residue is obtained from the distillation of the product of phosgenating toluene diamine to the corresponding toluene diisocyanate and has a toluene diisocyanate content of about 30% to about 70% by weight. The isocyanate-reactive compounds are useful in polyurethane formulations.
