Abstract

1406238 Tetrafluoroethylene polymer dispersions IMPERIAL CHEMICAL INDUSTRIES Ltd 22 Aug 1972 [17 Sept 1971 (2)] 43436/71 and 43437/71 Addition to 1354471 Heading C3P A tetrafluoroethylene polymer dispersion is prepared by comminuting and dispersing in a liquid a polymer powder prepared by irradiation, with a dose of at least 2 M Rads, of an unsintered coagulated dispersion grade polymer powder. In examples irradiated polytetrafluoroethylene was dispersed in light oil, trichlorotrifluoroethane, and water containing sodium lauryl sulphate and a mixture of carboxyl vinyl polymers or acrylic copolymers as thickening agents.
