| Abstract: | We use the PC‐SAFT equation of state to model the solubility of CO2 in various homopolymers. We also model the swelling ratio of the PP (polypropylene)‐CO2 mixture using PC‐SAFT and then compare the results with Sanchez‐Lacombe (S‐L) and Simha‐Somcynsky (S‐S) equations. The results show that PC‐SAFT can describe the solubility of CO2 in polymers very well. We compare two sets of parameters in the PC‐SAFT equation, Gross et al.'s and Chen et al.'s. As for the swelling ratio, PC‐SAFT using Chen et al. parameters is better than S‐L equation, which is commonly used by early researchers in studying the solubility of CO2 in polymers. © 2017 Wiley Periodicals, Inc.
