英文摘要This article investigated the melting behaviors, crystallization kinetics, and spherulitic morphologies of poly(butylene succinate) (pbs) and its copolyester (pbsr) modified with rosin maleopimaric acid anhydride, using wide-angle x-ray diffraction, differential scanning calorimeter (dsc), and polarized optical microscope. subsequent dsc scans of isothermally crystallized pbs and pbsr exhibited two melting endotherms, respectively, which was due to the melt-recrystallization process occurring during the dsc scans. the equilibrium melting point of pbsr (125.9 degrees c) was lower than that of pbs (139 degrees c). the commonly used avrami equation was used to describe the isothermal crystallization kinetics. for nonisothermal crystallization studies, the model combining avrami equation and ozawa equation was employed. the result showed a consistent trend in the crystallization process. the crystallization rate was decreased, the perfection of crystals was decreased, the recrystallization was reduced, and the spherulitic morphologies were changed when the huge hydrogenated phenanthrene ring was added into the chain of pbs. the activation energy (delta e) for the isothermal crystallization process determined by arrhenius method was 255.9 kj/mol for pbs and 345.7 kj/mol for pbsr.
