Title:
DISPERSANT
Document Type and Number:
Japanese Patent JPH06319976
Kind Code:
A
Abstract:
PURPOSE: To obtain a dispersant having dispersion performance which can make a disperse phase highly conc. and keep it by incorporating a condensate prepd. by reacting an arom. aminosulfonic acid, benzoic acid and formaldehyde to a bisphenol.
CONSTITUTION: A condensate is obtd. by reacting 1.0-1.5 mole arom. aminosulfonic acid, 0.5-1.0 mole benzoic acid and 1.5-3.0 mole formaldehyde to 1.0 mole bisphenol in an aqueous medium in the presence of alkali. As a dispersant contg. this condensate in the bisphenol exhibits excellent dispersion performance, the concn. of the disperse phase is made highly conc. and a cement compsn. wherein this dispersant is used exhibits excellent fluidity-keeping characteristics.
