摘　　要：聚羧酸系减水剂以低掺量、高减水率以及良好的保坍性等突出优势被广泛应用于混凝土工程。以大单体直接共聚法、聚合后功能化法、原位聚合与接枝法和断裂链转移聚合法为主线,综述了聚羧酸系减水剂不同合成方法的研究现状,探讨了当前聚羧酸系减水剂合成中存在的问题。Polycarboxylate superplasticizer is widely used in concrete engineering due to its low dosage,high water reducing rate and good slump retention.Based on the methods of macromonomer direct copolymerization,functionalization after polymerization,in-situ polymerization and grafting,and broken chain transfer polymerization,this paper reviews the research status of different synthesis methods of polycarboxylate superplasticizer and discusses the problems.
