Abstract

Corrugated separators for electrical accumulators are prepared from a plastic mass of polyvinyl chloride or a mixed polymer made mainly from vinyl chloride. The mixed polymer may contain vinyl acetate or acrylic acid derivatives such as acrylic nitrile, or the polyvinyl chloride may have been after-chlorinated. In examples, suitable mixtures for the preparation of separators comprise (1) an interpolymer of vinyl chloride and an acrylic acid ester with Black Lake, (2) an interpolymer of vinyl chloride and vinyl acetate with iron oxide black and a softener, and (3) after-chlorinated polyvinyl chloride and a pigment and softener.
