    • 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.
