It is proposed that melt-extrusion of poly(3-hydroxybutyrate-co-3hydroxyvalerate) at varying processing temperatures and screw speeds causes changes in the atomic positioning of the oxygen atoms in the helix structure due to torsion of the main chain bonds.

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
