摘要	A polybutadiene sulphone consists of a plurality of units of formula in which the sulphur content (as sulphone) is 27 to 32 grams per gram equivalent weight of polymerized butadiene and the polymerized butadiene consists of at least 85% butadiene units connected in the 1,4 position. The polymer is prepared by extruding into a reaction medium containing sulphur dioxide a solution of a butadiene polymer which contains at least 85% of the repeating units in the 1,4 position and containing also a hydroperoxide catalyst, e.g. tertiary butyl-hydroperoxide.
