Methods for probe analysis of EPR-spectroscopy, differential scanning calorimetry (DSC) and the X-ray analysis (XRD) at high angles, as well as UV-spectroscopy examined the molecular dynamics, structure, diffusion, mechanical properties, ozone oxidation of copolymer of hydroxybutyrate with chitosan . Study on copolymer hydroxybutyrate and chitosan and their mixed compositions showed that, since 30% of SGS in the mix, on the order of time increases the correlation time that indicates a sharp slowing molecular movement, and according to the DSC and the degree of crystallinity is decreased stepwise SAR. Decreases and the diffusion coefficient of rifampicin with the growth of polyhydroxybutyrata in mixture compositions.The effect of water, limited in time (1 h), on mixed compositions at 70 0C is accom-paned by increasing the molecular mobility of the probe in the system. Crystallinity change in complex ways.
