The temperature dependency of water vapor sorption and diffusion in poly(3-hydroxybutyrate) (PHB) was studied for the first time. Equilibrium sorption and diffusion kinetics were determined by a quartz McBain's vacuum microbalance technique in the temperature range of 303-333 K. A probability of wat
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
The effect of the preparation technique on the sorption-diffusion parameters of poly(3-hydroxybutyrate) (PHB) films was studied. The films formed by a singlestage technique have an axial texture of the crystalline phase, with the polymer chain oriented predominantly perpendicularly to the film plane
The sorption and diffusion of water vapor in poly(ethylene terephthalate) (PET) film were measured by applying a thermogravimetric analyzer (TG-DTA), which customarily has been used to detect the weight loss of a sample with the increase of temperature under a given atmosphere. In this case, we dete
