Notes:
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.
