Abstract

A new polycarboxylic acid-based superplasticizer(PSStNa-b-PAANa-b-PMPEG) was synthesized via the combination of atom transfer radical polymerization(ATRP) and resin exchanged technology. PSStNa-b-PAANa-b-PMMA was prepared using PSStNa-b-PAANa as macromolecule initiator by atom transfer radical polymerization (ATRP) of methyl methacrylate, and then reacted with methoxypoly (ethylene glycol)(MPEG) to synthesize triblock copolymer. The molecule structure of polycarboxylic acid-based superplasticizer was studied by FT-IR and ¹H-NMR. And then the influence of reaction time on the fluidity of cement paste was investigated. The result shows that our design is successful and the product reaction time with 26 h has the best performance in this way.
