Ethylenesulfones sulfones

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]

A measure of the relative reactivities of the monomers involved in copolymerization is reflected in their reactivity ratios and r2, the subscripts referring to monomers 1 and 213. Thus, when monomer 2 was sodium ethylenesulfonate, r2 was found to be close to zero while r (acrylamide) = 14.9 and r1 (sodium acrylate) = 5.8. A similar sluggishness in copolymerization with less-polar monomers was also found for other sulfonates. Izumi and coworkers studied the copolymerization of sodium allylsulfonate (MJ with acrylonitrile (M2) in dimethyl sulfoxide (DMSO) and DMSO-water mixtures. They found considerably lower values for r2 as compared to in aqueous DMSO and attributed it to lack of homogeneity , although no phase separation was observed in this medium14. [Pg.881]
