Description

It is well known that poly (butylene succinate) (PBS) is one of the biodegradable polymers. As PBS is crystalline, the polymer in a suitable organic solvent is expected to convert to a thermoreversible gel. In this study, the Flory-Huggins interaction parameter (χ12) between PBS and solvent was measured as a function of temperature by an inverse gas chromatography (IGC) measurement. The gelation of the PBS/solvent system was discussed from the viewpoint of the magnitude of χ12. The parameter χ12 measured for each PBS/organic solvent system increased slowly with decreasing temperature. The sol-gel transition of PBS solution took place when the parameter χ12 between PBS and solvent became slightly larger than 0.5. In the PBS/solvent system with χ12>>0.5, the liquid/solid phase separation occurred macroscopically and no gelation took place. The microscopic observation showed that many spherulites existed in the PBS gel.
