Ethylenesulfonic acid

The simplest monomer, ethylenesulfonic acid, is made by elimination from sodium hydroxyethyl sulfonate and polyphosphoric acid. Ethylenesulfonic acid is readily polymerized alone or can be incorporated as a copolymer using such monomers as acrylamide, aHyl acrylamide, sodium acrylate, acrylonitrile, methylacrylic acid, and vinyl acetate (222). Styrene and isobutene fail to copolymerize with ethylene sulfonic acid. [Pg.83]

Aral and Ise carried out the hydrolysis of dextrin in the presence of copolymers of vinyl alcohol and vinylsulfonic a increased from 1 to 1.4 at 80 °C, as the mole ratio of hydroxyethylene and ethylenesulfonic add repeat units wsB varied from nearly zero to 100. On the other hand, mixtures of pofy(ethylenesul-fonic add) 3 and poly(vinyl alcohol) possessed a catalytic efficiency lower than that of sulfuric add. [Pg.175]
