PROCESS FOR THE PRODUCTION OF METHALLYL SULPHONIC ACID AND SALTS THEREOF

摘要

Process for the production of methallyl sulfonic acid and salts thereof by reaction of isobutylene and a complex of sulfur trioxide and an N,N-dialkyl substituted amide of an aliphatic carboxylic acid or a N-alkyl substituted lactam wherein at least 1 mol of isobutylene is used for 1 mol of sulfur trioxide. The methallyl sulfonic acid and their salts are comonomers in the polymerization of olefinic compounds.
