<p>The present invention relates to copolymer dispersant comprising at least one polymerized monomer having CH2=C(R3)C(O)OXa(C2H4O)b-(C3H4O)c-R4 the general formula where a=0 or 1; when a=1, X is an akyl, aryl, or alkaryl diradical connecting group of 1-9 carbon atoms; b and c are independently selected from the range of 0-100 provided that b and c are not simultaneously 0; R3 is H or CH3; and R4 is preferably PO3H2. The present invention also relates to aqueous dispersion produced from such copolymer dispersants.</p> |
