聚羧酸类高效减水剂的研究现状与发展方向

Status and Development of Polycarboxylate Type Superplasticizer

介绍了目前聚羧酸类高效减水剂的结构特征与合成方法、分子结构与性能的关系、作用机理研究 ,提出一些亟待深入研究的问题及聚羧酸类高效减水剂今后的研究方向。

Polycarboxylate type superplasticizers ,a kind of water-soluber polymers which have backbone chains with anions(carboxyl,sulfonic acid group)and some other polar groups such as hydroxyl,ether,amide and amine,can be obtained from copolymerization of vinyl monomers.They have many useful properties. In this paper,the advances of the research on chemical structure and synthesis, relationship between molecule structure and performance , action mechanism were introduced in detail. Some urgent problems to be solved and the research trends have been put forward also.
