    Abstract: 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.

    Abstract: THE INVENTION RELATES TO AN ACRYLONITRILE GRAFT POLYMER HAVING IMPROVED AFFINITY FOR ACID DYES COMPRISING ACRYLONITRILE BEING GRAFT-POLYMERISED TOGETHER WITH OTHER ACRYLIC OR VINYL MONOMERS AND A LINEAR POLYETHER HAVING QUATERNISED NITROGEN ATOMS AS GRAFT BASE. THE GRAFT BASE HAS A MOLECULAR WEIGHT OF ABOUT 1,000 TO ABOUT 15,000 AND THE ACRYLONITRILE GRAFT POLYMER HAS A K-VALUE (ACCORDING TO FIKENTSHCER, CELLULOSE CHEMIE 13, (1932), PAGE 58) OF FROM 70 TO 100. IN THE PROCESS OF PREPARING SAID ACRYLONITRILE GRAFT POLYMER ACRYLONITRILE AND OTHER COPOLYMERISABLE COMONOMERS ARE GRAFT-POLYMERISED IN THE PRESENCE OF A GRAFT BASE CONSISTING OF A LINEAR POLYETHER HAVING QUATERNISED NITROGEN ATOMS.
