摘要:A two step process for the preparation of polymers which contain an easily controllable amount of sulfonate groups. In the first step, a copolymerization or a graft copolymerization is carried out using a controlled amount of an epoxy group containing monomer, said monomer being an ester of 2,3-epoxy propyl alcohol and acrylic acid. In a second step, the epoxy groups of the polymer prepared in the first step are, via ring opening reaction, partially or fully sulfonated by means of sulfite ions in aqueous solution in the presence of a quaternary ammonium salt as a catalyst.
