Title:
PHOSPHORIC ESTER POLYMER
Document Type and Number:
WIPO Patent Application WO/2006/006732
Kind Code:
A1
Abstract:
A process by which a dispersant for hydraulic compositions can be produced on an industrially practical level. A specific monomer (1) having a polyoxyalkylene group, a phosphoric monoester monomer (2), and a phosphoric diester monomer (3) are copolymerized at a pH of 7 or lower. Thus, a phosphoric ester polymer suitable for use as a dispersant for hydraulic compositions is obtained.
