摘要

目的　研究纤维素衍生物与低分子体系溶剂化程度对热力学相容性影响 .方法　对增塑体系组分间热力学相容性进行理论分析并通过实验测试 .结果　建立了半刚性链纤维素衍生物增塑体系组分相容性界限与溶剂化参数间关系 .结论　在溶剂化状态下

影响纤维素衍生物增塑体系热力学相容性的主要因素是溶剂化程度

而溶剂化程度与小分子、纤维素衍生物中葡萄糖环基摩尔体积比值 V1 / V2 和溶剂化参数 z值有关 .

Abstract

Aim To study the effect of the solvation in cellulose derivative solutions on the thermodynamic compatibility. Methods The theoretical analysis and the experiment data of the thermodynamic compatibility are used. Results An equation relating the stoichiometry of solvation between solvents molecule and cellulose derivative to the limit of compatibility was established. Conclusion The main factors of effect on the thermodynamic compatibility is the extent of solvation in the state of solvation. The extent of solvation is connected with molar volume ratio of solvent to glucopyranose ring and solvation parameters z .
