摘要：

Copolyesters based on isosorbide and butanedioic acid in combination with monomers such as adipic acid and dimethyl terephthalate, poly(isosorbide--butanedioic acid) (and --adipic acid) and poly(isosorbide--butanedioic acid--dimethyl terephthalate), were synthesized and characterized. Linear OH-functionalized polyesters were obtained via melt polyesterification of dicarboxylic acids with OH-functional monomers. The type of end-group was controlled by the monomer stoichiometry and hydroxyl functional group is formed in time. Average molecular masses of synthesised polyesters were measured by gel permeation chromatography. The glass transition temperatures and thermal stability of the obtained polyesters were effectively adjusted by varying polymer composition and molar mass. Addition of adipic acid or dimethyl terephthalate increased glass transition temperatures of obtained polyesters. Thermal stability of obtained polyester slightly increases by the increasing of dimethyl terephthalate content. Molecular structures of obtained polyester were assessed by Fourier transform infrared spectra and H-1 NMR spectroscopy.
