Abstract

A molding composition which is essentially composed of a mixture of at least two polymers based on vinyl chloride and at least one water-soluble surfactant is described. One of the polymers is a sinterable vinyl chloride/alkyl acrylate copolymer which can contain, in addition, polymerized units of vinyl acetate and ethylene. At least one further polymer is a vinyl chloride polymer which can contain up to 5% by weight of polymerized units of vinyl acetate and ethylene. The molding composition is suitable for the production of sintered, porous, flexible moldings, in particular separator compartments for electric cells.
