Abstract The PC-SAFT Equation of State is applied here to study polymer – blowing agent phase equilibrium in various systems of industrial interest. Where required, PC-SAFT parameters of blowing agents and polymers are obtained by regression to experimental data. Gas solubility and swelling ratio of polymer material predicted by PC-SAFT is seen to agree well with experiments. The PC-SAFT model is then extended to predict gas solubility and swelling ratio in a broad range of operating conditions, well beyond those reported by corresponding experiments. PC-SAFT has also been robust in predicting gas solubility in random copolymer or gas blend foaming systems showing additional degrees of freedom in foam formulation design, and requiring only inputs from the individual homopolymer or single blowing agent systems. From this work, PC-SAFT offers a reliable method to extrapolate existing measured data and provide guidelines for screening and design of new products and processes.

使用 PC-SAFT 状态方程预测橡胶聚合物中发泡剂的溶解度和溶胀比

摘要 这里应用 PC-SAFT 状态方程来研究各种工业系统中的聚合物 - 发泡剂相平衡。在需要时，发泡剂和聚合物的 PC-SAFT 参数通过回归实验数据获得。可以看出 PC-SAFT 预测的聚合物材料的气体溶解度和溶胀比与实验非常吻合。然后扩展 PC-SAFT 模型以预测各种操作条件下的气体溶解度和溶胀率，远远超出相应实验报告的范围。PC-SAFT 在预测无规共聚物或气体共混发泡系统中的气体溶解度方面也很可靠，显示出泡沫配方设计的额外自由度，并且只需要来自单个均聚物或单一发泡剂系统的输入。从这部作品中，
