CONCRETE FLOW IMPROVERS AND WATER REDUCERS
The present invention relates to a process for preparing 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 esterification of the polymer obtained to give a homopolymer or copolymer ester, and to the use thereof as additive, flow improver and water reducer.
本发明涉及一种制备聚(甲基)丙烯酸的方法，其特征在于使来自(甲基)丙烯醛合成的含(甲基)丙烯酸的工艺料流经历自由基聚合。本发明还涉及所得聚合物的酯化以产生均聚物或共聚物酯，及其作为添加剂、流动改进剂和减水剂的用途。
