Abstract
A processing agent for polyvinyl chloride and other thermoplastic polymers. The processing agent is a copolymer which contains a monomer whose homopolymer has a T.sub.g .gtoreq.65 C. and contains 3 to less than 75% by weight of a comonomer which has a C.sub.8 -C.sub.22 alkyl component. The alkyl component should be apportioned in such a fashion that the transmission of the copolymer in ethyl acetate is at least 90% in the case of a 10% solution.
