摘要

本文进行了氯乙烯在氯相/高聚物 (PVC

EVA

EVA-g-VC) 间相平衡的研究。实验数据用三种数学模型作了处理:Flory-Huggins 经典模型、Prigogine-Flory 自由容积模型和本文作者提出的线性模型。氯乙烯在高聚物中的溶解度按三种模型的计算值与实验结果都符合得很好。而且

结果表明

线性模型具有精确易用的优点

Prigogine-Flory 模型完全适用于 VC/PVC体系

VC在EVA-g-VC接枝共聚树脂中的溶解度服从加和性规律。

Abstract

The equilibria of VC between vapor phace and PVC

EVA or EVA-g-VC phase were studied at 60℃ in water slurries. The experimental data were treated with three mathematical models: Flory-Huggins' classical model

Prigogine-Flory's free-volume model

and the author's linear model. The calculated values of the solubility of VC in the polymers agreed well with the experimental results. Moreover

it was shown that the free-volume model is applicable to VC/PVC system

the linear model has the advantage of adequate accuracy and simp-licity in use

and the solubility of VC in EVA-g-VC follows the rule of additivity.
