摘要： A polyurethane/urea/thiourea latex having a narrow molecular weight polydispersity and sub-micron particle size can be prepared by first preparing a high internal phase ratio (HIPR) emulsion of a polyurethane/urea/thiourea prepolymer, then contacting the emulsion with a chain-extending reagent under such conditions to form the polymer latex.

摘要： A polyurethane-polymer composition suitable for preparing a lightweight tire support includes at least one isocyanate, at least one polyol, and at least one chain extender. A polyurethane-polymer composition can also include an additive such as a catalyst, a filler, a surfactant, a colorant, and a mold-release agent. A lightweight tire support can be prepared from a polyurethane-polymer composition by, for example, reaction injection molding. Such a tire support desirably has temperature stability and load-bearing capability.

摘要： The present invention is a polyurethane pressure sensitive adhesive composition which is useful in preparing articles having a layer of a pressure sensitive adhesive. The pressure sensitive adhesive of the present invention can be washed with water, or optionally a detergent solution, and can then recover at least 60 percent of its original adhesion after is is dried.
