The process of forming a laminate by molding, preferably either by compression or injection molding, a polymer which is incompatible with PVF2 onto the surface of a preformed laminate sheet of a PVF2 and a polyalkyl methacrylate, with the preformed laminate have been previously obtained by the coextrusion of the PVF2 and polyalkyl methacrylate.

Ultra-high molecular weight polyethylene powder is heated at a temperature between its crystalline melting point and about 275 DEG C. for a short period of time ranging from about one minute to about thirty minutes to obtain a molding powder having properties which facilitate the subsequent step of compression molding. Compression molded pieces made from heat-treated powder have better transparenc...
