Abstract

PURPOSE:To obtain the titled dispersion in high efficiency, by dispersing calcium carbonate in an aqueous medium using, as the dispersant, a combination of a maleic anhydride/alpha-olefin copolymer neutralization product and water-soluble anionized modified polyvinyl alcohol. CONSTITUTION:The objective aqueous dispersion can be obtained by dispersing 100pts.wt. of calcium carbonate in an aqueous medium using a dispersant consisting of (A) 0.1-2pts.wt. of a neutralization product of a copolymer with an average molecular weight of 2,000-80,000 prepared by copolymerization between 1mol. of maleic anhydride and 0.7-1.2mol. of a 2-7C alpha-olefin (e.g. propylene) and (B) 0.03-1pt.wt. of a water-soluble anionized modified polyvinyl alcohol with a polymerization degree of 30-700 saponification degree of 30-100mol.% and anionized modification degree of 0.5-20mol.% (e.g. water-soluble sulfonated modified polyvinyl alcohol).
