Water sorption and diffusion have been investigated in poly(3-hydroxybutyrate) (PHB) and three poly(3-hydroxybutyrate-co-3-hydroxyvalerate) copolymers [P(HB-HV)] by means of a Cahn electromicrobalance. Permeability of these samples have been determined using a gravimetric permeation cell. Two experi
CO 2 sorption and diffusion in poly(3-hydroxybutyrate) and three poly(3hydroxybutyrate-co-3-hydroxyvalerate) copolymers were investigated gravimetrically at temperatures from 25Β°to 50Β°C and pressures up to 1 atm. The sorption behavior proved to be linear for all the copolymers studied. An additional
## Abstract The preparation and properties of nanocomposites, consisting of a poly(3βHydroxybutyrateβ__co__β3βhydroxyvalerate) and an organophilic clay are described. The effect of organophilic clay on the crystallization behavior of (PHBV) was studied. A differential scanning calorimeter (DSC) was
