【 摘 要 】

The synthesis of poly(3-hydroxybutyrate/3-hydroxyvalerate/3-hydroxyhexanoate) [P(3HB/3HV/3HHx)] and poly(3-hydroxybutyrate/3-hydroxyhexanoate/diethylene glycol) [P(3HB/3HHx/DEG)] by Cupriavidus eutrophus B10646 was studied. Cultivation conditions of Cupriavidus eutrophus B10646 enabled production of high biomass yields and high content of the polymer. Three component copolymers [P(3HB/3HV/3HHx) and P(3HB/3HHx/DEG)] were synthesized with different content of 3HHx monomers. The physical and chemical properties of copolymers, including the degree of crystallinity, molecular weight and temperature characteristics and surface properties of the film samples were studied
