| 520 | _aA series of atactic amorphous oligo[R , S - hydroxybutyric acid] with different molar mass was synthesized in order to blend this materials with bacterial crystalline polyhydroxybutyrate (PHB) The glass transition of the mobile amorphous phase fraction and the amount of rigid amorphous fraction were determined by calorimetric and dielectric methodsThe crystallization kinetics was observed by polarizing microscope and compared with the prediction of the theory of Boon and AzcueTernary blends of PHB with polyvinylacetate and oligomers were also investigatedTensile tests at different temperature (20 oC - 90 oC) have been carried out with respect to technical applications of these blends | ||
