Abstract

Polymeric materials are prepared by causing vinylidene chloride, by itself or together with one or more other polymerizable compounds containing the group >C=CH- which are not present in preponderating amount, to polymerize in an aqueous medium in the presence of persulphuric acid or a water-soluble persulphate and of a water-soluble thiosulphate. The invention is carried into effect in the manner described in Specification 573,369 except that the water-soluble compound capable of taking up molecular oxygen is replaced by the water-soluble thiosulphate. In examples, vinylidene chloride by itself or in the presence of vinyl chloride is polymerized in aqueous emulsion in the presence of ammonium persulphate and sodium thiosulphate. Specifications 525,048 and 532,308 (both as accepted and as open to inspection under Sect. 91) also are referred to.
