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.
这项发明涵盖了一种新颖的方法,用于制备氨基,烷基氨基和季铵酸的羟基聚合物酯,并在多个工业领域中使用,包括用作纸张或纸板制造中的添加剂。羟基聚合物(最好是淀粉)的酯化是在半无水条件下进行的,通过加热均质混合物来完成羟基聚合物和试剂的反应。
