Cationic polysaccharide derivatives are prepared by reacting a polysaccharide with a polycationic reagent having one polysaccharide reactive group and at least two cationic groups. Suitable reagents include polycationic alkyl, aryl alkaryl, cycloaliphatic, or heterocyclic amines, some of which are novel compositions. The polycationic polysaccharide derivatives prepared from these reagents are useful in the manufacture of paper.
阳离子多糖衍生物的制备方法是将多糖与具有一个多糖活性基团和至少两个阳离子基团的多阳离子试剂反应。合适的试剂包括多阳离子烷基、芳基烷芳基、环脂族或杂环胺,其中一些是新型组合物。用这些试剂制备的多阳离子多糖衍生物可用于造纸。
