Polysulfones by the Reaction of Allylic Compounds with Sulfur Dioxide

POLYSULFONES BY THE REACTION OF ALLYLIC COMPOUNDS WITH SULFUR DIOXIDE 

In 1898 Solomina [1] reported that sulfur dioxide reacted with allyl alcohol, allyl methyl ether, and allyl ethyl ether [1]. Solomina reported that carboxyl, halide, and ester groups inhibited the reaction [1]. In 1935 Ryden and Marvel [26] reported that sulfur dioxide did not copolymerize with allyl cyanide or 2-allyl-/i-cresol when peroxide-paraldehyde was used but did polymerize when ascaridole was added [62]. In a later publication Kharasch and Steinfeld reported that allyl chloride copolymerized with sulfur dioxide in the presence of ascaridole and aqueous hydrochloric acid [63]. 

Representative allyl monomer-sulfur dioxide copolymers and tiieir conditions for polymerization are shown in Table XVIII.
