본 발명은, 중합이 하나 이상의 관형 반응기 부분에서 이루어지는, 하나 이상의 수용성 개시제의 존재 하에 수성 매질 중에서 단량체 A 및 임의로 수용성, 모노에틸렌성 불포화 공단량체 (단량체 B) 의 자유 라디칼 중합에 의해 C-C에틸렌성 불포화 모노- 또는 디카르복실산 및 이의 무수물 및 염 (단량체 A) 의 고분지형 단독- 또는 공중합체의 제조를 위한 연속 공정에 관한 것이다. 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.
