Cotelomers of vinylchloride and other monomers (acrylate esters, diethyl maleate, diethyl fumarate, ethylene, propylene, and butene‐1) have been prepared in order to evaluate their properties as plasticizers for poly(vinyl chloride). With the electron‐acceptor ester‐monomers, cotelomers with carbon tetrachloride of an average molecular weight of 500–900 were obtained, using iron chloride as the catalyst. Ethylene, propylene, and butene‐1 gave lower molecular weights and a considerable amount of distillable telomers. Ethylene, vinyl chloride, and carbon tetrachloride gave cotelomers with a molecular weight in the range 400–750, when the telomerization was initiated by ethanolamine or by azobisisobutyronitrile. These initiation systems gave a much reduced volatile fraction.
