摘要：A continuous process for making a comb-branched copolymer of an acrylicmonomer and a polyether macromonomer is disclosed. The process is performed bycontinuously feeding a reaction zone with a monomer stream that contains an acrylic acidand a polyether macronomer, and an initiator stream. The comb-branched copolymermade thereby performs better as water reducing agent in cement compared to thatmade by a batch process.
