Abstract:In this work, a novel AaBAb−type triblock polycarboxylate superplasticizers (PCEs) with well defined molecular structures were designed and synthesized, firstly, by reversible addition−fragmentation chain transfer (RAFT) polymerization, to explore the structure–property relationship PCEs in the β−hemihydrate gypsum (β−HH) system. Three PCEs with the same molecular weight and different structure were obtained by changing the feed ratio of the RAFT agent, initiator, and monomer. The effect of the chemical struct… Show more
