| Polyurethane polyether-based elastomers are described which are thermoplastic, recyclable and have increased high temperature resistance which permits fabrication by injection molding. The elastomers are the product of reaction of 4,4'-methylenebis(phenyl isocyanate), a particular group of polypropylene oxide-polyethylene oxide block copolymers and an extender [straight chain aliphatic diols C.sub.2-6 or the bis(2-hydroxyethyl ether) of hydroquinone or resorcinol]. The block copolymers have at least 50 percent primary hydroxyl groups, a pH in the range of 4.5 to 9, a content of alkali metal ion less than 25 ppm and a molecular weight of 1000 to 3000. The minimum ethylene oxide (E.O.) residue content (percent by weight) of the polyether for any molecular weight (M.W.) is governed by the equation: ##EQU1## In a particularly preferred embodiment the elastomers are prepared by replacing up to 25 percent by equivalents of the extender by certain diols (polyethylene glycols up to 1500 M.W. preferred). | ||||||

| Solid particle-form, polymerizable or cross-linkable, multi-functional polymeric material containing blocked isocyanate groups wherein the blocked isocyanate groups making up said polymeric material comprise only a portion of the total isocyanate groups to produce said polymeric material, such as extrudable, thermosettable powdered blocked polyurethane (PBP) has been prepared. This material is useful per se for the manufacture of articles and may be added in combination with other materials, such as thermoplastic resins, e.g. polyethylene, polyvinyl chloride, for improving the usefulness, versatility and physical and/or chemical properties thereof. The polymeric material, such as PBP, is useful as a coating on metal and non-metallic surfaces, e.g. glass or fibrous surfaces, either as a protective coating or for the purpose of laminating such surfaces to another surface. The polymeric material, such as PBP, may be manufactured by reacting a liquid reaction admixture comprising a partially blocked polyurethane prepolymer with a chain extending reactant under conditions such that the reaction admixture is reacted in dispersed form with the result that the reaction product is recoverable in solid particle-form as said PBP. | ||||||
