Abstract: Polymers of vinyl chloride are stabilized by the incorporation therein of 0,05 to 5 weight per cent of a stannonoic and/or thiostannonoic acid condensation product having the general formula (RSnO1,5)n or (RSnS1,5)n or (RSnO1,5)m. (RSnS1,5)n wherein R is a C1-20 alkyl, cycloalkyl or aryl group, and n or m+n is an integer from 2 to about 1,000, or of a mixture of such products. Their preparation is described in Specification 890,283. The polymers may be vinyl chloride homopolymers, copolymers of at least 50% vinyl chloride, and mixtures containing at least 50% of such polymers. Comonomers specified are vinylidene chloride, vinyl acetate and stearate, acrylates (e.g. butyl acrylate), maleates (e.g. dicetyl maleate), and mixtures thereof. Other polymers which may be mixed with the vinyl chloride polymers are synthetic rubbers, e.g. copolymers of butadiene with acrylonitrile and/or styrene, and chlorinated or sulphochlorinated polyolefines or mixtures thereof. The stabilizers may be mixed with known organo-tin or other stabilizers. Other ingredients which are included in exemplary compositions are dioctyl phthalate; a montan-wax based lubricant and calcium stearate-The examples contrast the effectiveness of compounds of the above formulae wherein R is methyl, butyl, octyl or phenyl with that of di. butyl-tin-bis-thioglycolic acid (2-ethyl-hexyl) ester in polyvinyl chloride, copolymers of vinyl chloride with vinyl acetate (13%), dicetyl maleate (25%) or butyl acrylate (30%), and mixtures of polyvinyl chloride with 15% of a terpolymer of butadiene/styrene (17%)/acrylonitrile (10%) and with 20% of a chlorinated low pressure polyolefine containing 40% chlorine. Specification 854,089 also is referred to.

Abstract: Plasticized polyvinyl or polyvinylidene chloride compositions are prepared by mixing an aqueous emulsion or dispersion, a dispersion in an organic solvent, or finely-powdered polyvinyl or polyvinylidene chloride, or a copolymer of vinyl chloride and an olefinic monomer, with an organic solvent solution of chlorinated or sulphochlorinated polyethylene, polypropylene, or copolymer of ethylene and propylene, and removing the solvent and water from the mixture. A solution of the polyolefine may be added to an aqueous emulsion of the polyvinyl chloride or vice versa, or alternatively finelypowdered polyvinyl chloride may be added to the polyolefine solution. Polyethylene prepared by the high or low-pressure processes may be used with solvents such as methylene chloride, chloroform, carbon tetrachloride, tetrachlorethane, benzene or toluene or mixtures thereof, with or without anion or cation emulsifiers. The mixtures may be freed of solvent by coagulating with, for example, calcium on lead chloride, by atomizing with steam or inert gas under reduced pressure, or by stirring with hot water. Other plasticizers and dyestuffs may be included in the composition.
