Popis:	Adsorption chromatography and GPC under isocratic and gradient conditions were used to investigate MMD and distribution according to types of functionality of oligomers of polybutylene terephalate-products of re-esterification of dimethylterephthalate with 1,4-butanediol. It was shown that a number of compounds are present in the mixture, including dimethylterephthalate, mono- and dihydroxybutylterephthalates and oligobutylene terephthalates. Results of chromatographic analysis were confirmed by direct identification of components of the mixture analysed using mass-spectrometry of field desorption.
