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