Abstract
Light-transmitting compositions containing (1) 50-99% by weight of polyvinylidene fluoride or a vinylidene fluoride copolymer and (2) 1-50% by weight of a copolymer of a vinyl fluoride monomer and at least one acrylate monomer selected from the group consisting of alkyl acrylates and alkyl methacrylates wherein the alkyl group contains from one to four carbon atoms.
Claims4
A composition consisting essentially of (1) 50-99% by weight of polyvinylidene fluoride or a vinylidene fluoride copolymer and (2) 1-50% by weight of a copolymer of 6 to 60 percent by weight of a vinyl fluoride monomer and 94 to 40 percent be weight of at least one acrylate monomer selected from the group consisting of alkyl acrylates and alkyl methacrylates wherein the alkyl group contains from one to four carbon atoms.
