Abstract

1,255,081. Polyvinylidene fluoride compositions. PENNWALT CORP. 23 Sept., 1969 [25 Sept., 1968], No. 46846/69, Heading C3P. A fluoropolymer composition comprises a thermoplastic vinylidene fluoride polymer having dispersed therein a particulate thermoplastic tetrafluoroethylene polymer, the tetrafluoroethylene polymer being present in an amount of from 0-5 to 2% by weight, based on the total weight of the two polymers, and having a particle diameter in the range of from 0À1 micron to 20 microns. The vinylidene fluoride and tetrafluoroethylene polymers may be the homopolymers or copolymers containing at least 90 mole per cent of the monomer and up to 10 mole per cent of comonomers, all the polymers being solid at room temperature and of high molecular weight. In the examples the compositions are prepared by mixing latices of the polymers, shear coagulating and drying; mixing polymer powders and mixing the polymer powders in a slurry of methanol and evaporating.
