Abstract: A flexible non-reticulated foam pad having on a surface thereof a polyurethane coating consisting essentially of a cured isocyanate-terminated prepolymer, the penetration of the prepolymer coating being no more than about 50 percent of the thickness of the flexible urethane foam. The coated surface provides an abrasive area which enhances its use in cleaning applications as well as increasing the resistance to tear propagation of the wet foam. In addition, the major portion of the foam pad is available for the release of cleaning and sanitizing agents or the absorption of liquids such as water. The novel foam pads are suitable for household, institutional and industrial use.

Abstract: 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.

Abstract: 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.
