| titleOfInvention | Cement dispersant |
| abstract | PURPOSE: To enhance the slump loss-preventive properties of cement composition by utilizing the oxidative copolymer of both naphthalenesulfonic acid (salt), alkyl naphthalenesulfonic acid (salt) and an aromatic compd. contg. a hydrophilic group as the essential component of a cement dispersant. n CONSTITUTION: (a) Naphthalenesulfonic acid, alkyl naphthalenesulfonic acid, formalin condensate thereof or salts thereof arc allowed to react with (b) an aromatic compd. having a hydrophilic group by oxidative polymerization. A slump loss-prevention type cement dispersant is produced by incorporating the obtained oxidative copolymer as an essential component. As the component (b), a benzene derivative and a naphthalene derivative are shown which have one or more kinds of hydrophilic group such as hydroxyl group, carboxyl group, amino group and sulfo group. The oxidative copolymer is obtained by oxidative polymerization reaction due to metallic oxide such as e.g. permanganate. n COPYRIGHT: (C)1991,JPO&Japio |
