Process for treating polyvinylidene fluoride and resulting products

摘要

The present invention relates to a process for treating polyvinylidene 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 100 DEG to 300 DEG C. for a time sufficient to evaporate said solvent.
