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. By wide angle X-ray scattering it was obse
