Abstract
The crystallization and solid-state polymerization (SSP) of poly(aryl ester)s was investigated. Oligomers with different end-groups were prepared by degradation of commercially available poly(aryl ester)s. The SSP of these oligomers was carried out after crystallization and under reduced pressure, in the presence of various catalysts. Polymers were characterized by means of their inherent viscosities and thermal properties. It has been found that Ti(OiPr)4 was a better catalyst for SSP. The structures and morphologies of semicrystalline poly(aryl ester)s were investigated by X-ray diffraction and differential scanning calorimetry (DSC).
