본 발명은 (메트)아크롤레인 합성으로부터의 (메트)아크릴산 함유 공정 스트림에 유리 라디칼 중합이 실시됨을 특징으로 하는 폴리(메트)아크릴산의 제조 방법에 관한 것이다. 본 발명은 또한 얻어진 폴리머를 에스테르화하여 호모폴리머 또는 코폴리머 에스테르를 제공하는 것, 및 첨가제, 유동성 향상제 및 감수제로서의 이것의 용도에 관한 것이다. The present invention relates to a process for preparing a poly(meth)acrylic acid, characterized in that a (meth)acrylic acid-containing process stream from (meth)acrolein synthesis is subjected to free-radical polymerization. The invention also relates to the esterification of the polymer obtained to give a homopolymer or copolymer ester, and to the use thereof as additive, flow improver and water reducer.
