Abstract
A procedure for sulfonating a polymer containing olefinic unsaturation by dissolving the polymer in an appropriate solvent that carries out the sulfonation reaction and recovering the sulfonated polymer, characterized in that the polymer is sulfonated by reaction with a SO3 complex that is prepared by reacting a base Lewis containing a nitrogen phosphorous donor, or oxygen and sulfur trioxide donor and that sulfonation is carried out to produce a polymer having a sulfonation level of 0.08 to 20 mole percent.
