摘要：

The changes of parameters of the unit cell of biopolymer poly(beta-hydroxybutyrate) (PHB) during heating from room temperature to the melting temperature are measured and results are presented here. The considerable increase of value of parameter a with increase of temperature is noticed with coefficient of thermal expansion of (approximate to 1.4 +/- 0.3) x 10(-4)degrees C-1. In the same time the changes of parameters b and c are negligible. On the basis of wide-angle X-ray scattering diffractograms the coefficient k is determined to be 1.06 +/- 0.08 (Hermans-Weidinger method).
