POLYMER HAVING DISPERSING FUNCTION, POLYCARBOXYLIC ACID CEMENT DISPERSANT, PREPARATION METHOD THEREFOR AND USE THEREOF
A polymer having a dispersing function, a preparation method therefor and use thereof as a cement dispersant are provided. The polymer has a structural unit (a), a structural unit (b) and a structural unit (c). The structural unit (a) is provided by an unsaturated polyether, the structural unit (b) is provided by an unsaturated acid and/or a salt thereof and/or an anhydride thereof, and the structural unit (c) is provided by a silane and/or siloxane having a polymerizable group and no less than five carbon atoms. The molar ratio of the structural unit (a), the structural unit (b) and the structural unit (c) is 1:(1-20):(0.01-0.5); and the polymer has a weight average molecular weight of 20,000-90,000 g/mol.
