COPOLYMER FOR DISPERSANT FOR CEMENT, DISPERSANT FOR CEMENT, AND CEMENT COMPOSITION |
摘要 |
An object of the present invention is to provide a novel copolymer capable of exerting excellent dispersibility to various kinds of cement including cement having low fluidity (difficult cement), and a dispersant for cement and cement composition including the copolymer. The copolymer of the present invention is a copolymer obtainable by polymerizing polymer components including an unsaturated (poly)alkylene glycol ether monomer (a), an unsaturated carboxylic acid monomer (b), and an unsaturated cross-linkable monomer (c) or an unsaturated polymerizable monomer (d). |
