PROCEDIMENTO PER IL TRATTAMENTO DEL POLIFLUORURO DI VINILE AL FINE DI MIGLIORARNE L ADERENZA AD ALRI POLIMERI

摘要

The present invention provides a process for treating polyvinyl fluoride surfaces to enhance adhesion of other polymers thereto comprising applying to at least one surface thereof a solution consisting essentially of a coating polymer selected from a polyurethane or an alkyl polymethacrylate and at least one aprotic polar solvent in which said polymer is soluble, and exposing said surface to a temperature of from about 120 DEG C. to 230 DEG C. for a time sufficient to evaporate said solvent. The treated polyvinyl fluoride having an adhering intermediary surface of polyurethane or alkyl polymethacrylate usefully serves as a means to secure the polyvinyl fluoride to another polymer which otherwise would not adhere to polyvinyl.
