摘要：This invention covers a novel method for the preparation of hydroxy polymeresters of amino, alkylamino and quaternary ammonium acids and their use in severalfields of industry, including the use as additives in the manufacture of paper or
paperboard. The esterification of the hydroxy polymer, preferably starch, is performedunder semianhydrous conditions by heating homogenized mixtures of the hydroxypolymer and reagents.
