Abstract
Time resolved small angle X-ray scattering is used to probe the micros tructural changes occurring in a sample of poly(hydroxybutyrate), aged at room temperature, during a heating cycle designed to reverse any p hysical ageing. Evidence for the reversal of physical ageing is seen, but is unlikely to account for all the changes in mechanical propertie s in this polymer on storage at room temperature. (C) 1998 SCI.
