Аннотация: The properties of new five-component poly(hydroxyalkanoates) (PHA) formed by short-and medium-chain monomers synthesized by the bacterium Wautersia eutropha B5786 were studied by X-ray diffraction, IR spectroscopy, differential thermal analysis, and viscometry. The degree of crystallinity of PHA decreased from 72 to 57% as the molar fraction of hydroxyhexanoate increased from 2.5 to 18.0 mol%. The melting temperature (T m) and decomposition temperature (T d) of the multicomponent PHA are lower than those for poly(hydroxybutyrate), whose T m and T d are 168-170 and 260-265В°C, respectively. Both parameters of the multicomponent PHA decrease to 156 and 252В°C, respectively, as the hydroxyhexanoate mole fraction is raised. The effect of hydroxyhexanoate on the physicochemical properties of the PHA is similar to that of hydroxyvalerate observed previously. В© 2007 Pleiades Publishing, Inc.
