Abstract

The adhesion of polyvinylamine to wet cellulose was significantly enhanced by the presence of pendant phenylboronic acid groups. It is proposed that adhesion results from boronate ester formation with cellulose at pH > 8. Experiments with phenol derivatized polyvinylamine gave low adhesion supporting the fact that the boronate moiety was responsible for strong adhesion to never-dried cellulose surfaces.

摘要

通过引入侧苯基硼酸基团，聚乙烯胺对湿纤维素的粘附力显著增强。据推测，在pH > 8的条件下，粘附力源于与纤维素形成硼酸酯。对苯酚衍生化聚乙烯胺的实验显示其粘附力较低，这支持了硼酸部分是对未干燥纤维素表面产生强粘附力的原因这一事实。
