ABSTRACT:
A dispersion stabilizing agent for inorganic powder in an oily material, comprising a copolymer of (i) a polyoxyalkylene derivative represented by the general formula [I] below with (ii) one or more of maleic acid and the derivatives thereof selected from the group of maleic anhydride, maleic acid, maleic acid salts, maleic acid amides, and maleic acid esters, ##STR1## where Z is a residue of a compound having 2-8 hydroxyl groups, AO is an oxyalkylene group having 2-18 carbon atoms, R.sup.1 is an unsaturated hydrocarbon group having 2-5 carbon atoms, R.sup.2 is a hydrocarbon group having 1-40 carbon atoms, a=0 to 1000, b=0 to 1000, c=0 to 1000, l=1 to 8, m=0 to 2, n=0 to 7, (l+m+n)=2 to 8, (al+bm+cn)=1 to 1000, m/(l+n).ltoreq.1/2.
