Abstract: The theoretical values of one-dimensional solubility parameters and three-dimensional Hansen solubility parameters of poly(propylene carbonate) (PPC) and poly(lactic acid) (PLA) were calculated according to the group contribution method. The practical three-dimensional solubility parameters of PLA and PPC were derived by dissolution experiments. Solubility parameter distance (Ri) and Flory-Huggins interaction parameters (χAB) between solvents and polymers were analyzed by Teas diagram, meanwhile the compatibility between PPC and PLA was predicted and analyzed. The results showed that the values of one-dimensional solubility parameters for PPC and PLA were 20.37 (J/cm3)1/2 and 19.97 (J/cm3)1/2 respectively, and the values of Hansen three-dimensional solubility parameters and total solubility parameters (δd、δp、δh、δ) for PPC and PLA were 14.68 (J/cm3)1/2,7.37 (J/cm3)1/2,10.79 (J/cm3)1/2, 19.65 (J/cm3)1/2 and 15.45 (J/cm3)1/2,8.51 (J/cm3)1/2,11.02 (J/cm3)1/2,20.80 (J/cm3)1/2 respectively. Moreover, it could be find, from the dissolution experiment, that the δd、δp、δh、δ values of PPC and PLA were 16.94 (J/cm3)1/2,7.05 (J/cm3)1/2,6.75 (J/cm3)1/2, 19.56 (J/cm3)1/2 and 16.83 (J/cm3)1/2,6.40 (J/cm3)1/2,6.70 (J/cm3)1/2,19.21 (J/cm3)1/2, respectively. In the Teas plot, all the good solvents were located in a certain dissolution zone, while the poor solvents were located outside the zone. The Ri between polymers and good solvents was lower than the Ri of poor solvents. Moreover, the χAB between the polymers and good solvents was lower than 0.5, however χAB of poor solvents was higher than 0.5, which proved the results were credible. The solubility parameters of PPC and PLA derived from theoretical calculations and experimental methods were similar, and the absolute value of solubility parameters difference (Δ) lay in 0.077—1.300 (J/cm3)1/2, indicating the partial compatibility of PPC and PLA.
