Abstract: The sinterable polyvinyl chloride molding composition described is composed of 99.8 to 97% by weight, relative to the molding composition, of a suspension graft copolymer which is, in turn, composed of 99.7 to 85% by weight of polymerized vinyl chloride units, 0.9 to 10.5% by weight of polymerized ethylene units and 0.09 to 10.5% by weight of polymerized vinyl acetate units, with the proviso that the total of the polymerized ethylene and vinyl acetate units is 0.3 to 15% by weight, relative to the graft copolymer, and also 0.01 to 0.5% by weight, relative to the molding composition, of at least one free alkylarylsulfonic acid having 3 to 16 C atoms in the alkyl chain or at least one alkylsulfonic acid having 8 to 16 C atoms, and also 0.005 to 0.5% by weight, relative to the molding composition, of at least one water-soluble wetting agent which is free from metal ions and contains 12 to about 80 C atoms and a quaternary N atom which forms a salt with a carboxylic or sulfonic acid group. The molding composition gives sintered moldings, particularly separator plates for electrical cells, which have advantageous properties.

Abstract: A process is described for the preparation of mixtures for processing as plastisols or organosols, wherein at least one known plasticizer, at least one first vinyl chloride copolymer and at least one vinyl chloride homopolymer or a second vinyl chloride copolymer are mixed together, if appropriate with the addition of further known substances. The first copolymer is a specific vinyl chloride graft copolymer, of which 5 to 70% by weight are employed, relative to the total quantity of polymers present in the mixture. It contains 99.5 to 88% by weight of polymerized units of vinyl chloride, 0.1 to 11.9% by weight of polymerized units of vinyl acetate and 0.1 to 2.2% by weight of polymerized units of ethylene. The remaining polymer(s) employed is/are prepared in accordance with customary processes. Mixtures prepared in this manner produce plastisols or organosols which have a low viscosity and good stability on storage and which also enable uniform coatings to be obtained by applying a thin layer.
