疏水化水溶性纤维素衍生物

Hydrophobized water-soluble cellulose derivatives

疏水化水溶性纤维素衍生物是一类既含疏水基又含亲水基的新型纤维素改性物，性能独特，应用前景广阔。综述了迄今用于其制备与表征的若干方法，包括引人长链烷基流水基、碳氟疏水基、多环芳基流水基的大分子反应制备方法和应用核磁共振、紫外光谱、裂解／气相色谱技术的表征方法；同时对其溶解、增稠、表面活性、吸附及荧光光谱等主要物性进行了简要总结。

Hydrophobized water-soluble cellulose derivahves (HMWCD) are a naww kind of modified cellulosic polyrners with hath hydriphilic and hydrophobic groups, which halye unique properties and wide applicahon prospects.This paper review the preparation, charaterizaion and properties of HMWCD.It presents the preparation routes of alkyl HMWCD, fluocarbon HMWD and polycyclic arollatic HMWCD, the methods for detendning the amounts of hydriphobe incorporated by NMR, UV and degradation/GC, and HMWCD's properties including the solubility, enhanced viscosification, surface achvity, adsorbahility and fluorescence spectrographical property.
