METAL-ADHESIVE POLYVINYLIDENE FLUORIDE COMPOSITIONS

摘要

The present invention offers a method for improving the adhesion of polyvinylidene fluoride resins to metal materials. It consists of either adding to the said polyvinylidene fluoride resin and acrylic and/or methacrylic polymer having functional groups with bonding properties or affinity in respect of metal and an acrylic and/or methacrylic elastomer (not necessary when the resin is a vinylidene fluoride copolymer) or inserting between the said polyvinylidene fluoride resin and the metal a composition comprising a polyvinylidene fluoride, and acrylic and/or methacrylic polymer having functional groups with bonding properties or affinity in respect of metal and an acrylic and/or methacrylic elastomer (which must be present only when the polyvinylidene fluoride of the composition is not a copolymer).
