Abstract:
A vinylidene fluoride copolymer composition consisting essentially of (1) a thermoplastic copolymer of vinylidene fluoride and ethylenically unsaturated fluorine-containing comonomers, including at least 75% by weight of monomer units derived from vinylidene fluoride, and of (2) polyvinyl chloride in a weight ratio of said vinylidene fluoride copolymer to said polyvinyl chloride of at least 1.2, and of (3) an effective quantity of a methacrylic polymer including at least 55% by weight of methyl methacrylate to ensure compatibility between said vinylidene fluoride copolymer and said polyvinyl chloride, wherein said copolymer composition exhibits a lower dielectric constant and lower dielectric losses at frequencies of 1 MHz and above than a composition consisting essentially of the vinylidene fluoride copolymer.
