Abstract

See full text

The present invention relates to a continuous process for the manufacture of highly-branched homo- or copolymers of C3-C8 ethylenically unsaturated mono- or dicarboxylic acid as well as the anhydrides and salts thereof (monomer A) by means of free-radical polymerization of monomer A and optionally water-soluble, monethylenically unsaturated comonomers (monomer B) in an aqueous medium in the presence of at least one water-soluble initiator, wherein the polymerization takes place in at least one tubular reactor segment.
