Bl. Hurrell et Re. Cameron, A WIDE-ANGLE X-RAY-SCATTERING STUDY OF THE AGING OF POLY(HYDROXYBUTYRATE), Journal of Materials Science, 33(7), 1998, pp. 1709-1713
The ageing of poly( hydroxybutyrate) at room temperature has been stud
ied using wide-angle X-ray scattering. The observed unit-cell paramete
rs and crystal density did not change on ageing. A small increase in c
rystallinity was observed during the first 32 h storage. No change in
crystallinity was detectable after this time. These results are discus
sed in the light of theories relating to the embrittlement of poly( hy
droxybutyrate). (C) 1998 Chapman & Hall.
