Abstract
The benzoyl peroxide initiated cooligomerization of sulfur dioxide with octene-1 in the presence of bromotrichloromethane was investigated. Alternating copolymers and oligomers having 1:1 composition with respect to sulfur dioxide and octene-1 were isolated from the reaction mixture. The oligomers were fractionated by thin-layer chromatography and the molecular weight, IR spectra and end group analyses of the fractions determined. It was found that the structure of the oligomers was mainly C6H5–(–SO2–octene–1–)n–Br. The oligomer seems to be formed by the reaction of phenyl radicals (originated from a fragment of benzoyl peroxide) and a monomer complex of sulfur dioxide and octene-1, not by the alternate addition of sulfur dioxide to the octene-1 radical or of octene-1 to the sulfur dioxide radical.
