✦ Synopsis

Time resolved small angle X-ray scattering is used to probe the microstructural changes occurring in a sample of poly(hydroxybutyrate), aged at room temperature, during a heating cycle designed to reverse any physical ageing. Evidence for the reversal of physical ageing is seen, but is unlikely to account for all the changes in mechanical properties in this polymer on storage at room temperature.
