ABSTRACT:
Substantially alternating 1:1 copolymers of olefinically unsaturated sulfonate salts such as sodium methallylsulfonate and .alpha., .beta.-unsaturated aliphatic dicarboxylic acid anhydrides such as maleic anhydide are produced by free radical polymerization using a polar non-reactive organic solvent such as acetic acid. The copolymers and their derivatives are useful as water-soluble dispersants.
