| 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 resin, e.g. polyethylene, polyvinyl cloride, 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. | ||||||
