Abstract

1,171,245. Vinylidene chloride copolymer composition. IMPERIAL CHEMICAL INDUSTRIES Ltd. 10 May, 1968 [18 May, 1967], No. 23216/67. Heading C3P. A vinylidene chloride copolymer composition is prepared by polymerizing a monomeric mixture consisting of (i) vinylidene chloride and from 7 to 12% by weight of a comonomer selected from alkyl acrylates in which the alkyl group contains up to 4 carbon atoms and acrylonitrile, based on the weight of the monomeric mixture, or (ii) vinylidene chloride and 15 to 25% by weight of vinyl chloride based on the weight of the monomeric mixture, in an aqueous medium using a monomer-soluble, free radical yielding catalyst and thereafter separating the copolymer thereby formed from the aqueous medium, up to 5% by weight, based on the weight of the vinylidene chloride copolymer, of polytetrafluoroethylene in the form of an aqueous dispersion being added to the aqueous medium before the copolymer is separated therefrom. Preferably the polytetrafluoroethylene dispersion is added after the pressure in the polymerization vessel has started to fall. In the example vinylidene chloride is polymerized with methyl acrylate in the presence of distilled water, partially hydrolysed polyvinyl acetate and lauroyl peroxide. Shaped articles, e.g. bottles, may be made by melt extrusion.
