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.
阳离子多糖衍生物是通过将多糖与至少具有一个多糖反应基团和至少两个阳离子基团的多阳离子试剂反应制备的。适用的试剂包括多阳离子烷基、芳基、烷芳基、环脂肪或杂环胺类,其中一些是新颖的组合物。从这些试剂制备的多阳离子多糖衍生物在造纸制造中很有用。
