ABSTRACT:
This invention relates to the use of bisulfite-terminated oligomers as dispersants for solid particulate matter, i.e., low molecular weight bisulfate-terminated polymers containing carboxylate groups and either cyano or carbomethoxy moieties are improved dispersants for solid particulate matter like pigments such as titanium dioxide, clay, calcium carbonate, talc, and zinc oxide, as well as for organic pigments. Particularly, these dispersants have been found useful for stabilizing paper coating compositions.
