摘要：

A combined study of X-ray diffraction, differential scanning calorimetry and density measurements in copolymers of 3-hydroxybutyrate and 3-hydroxyvalerate is presented. It is shown that the unit cell volume expands linearly with the comonomer content in the polymer. The reduction in the enthalpy of fusion is interpreted in terms of limited co-crystallization of the two monomers. The amount of 3-hydroxyvalerate in the crystals has been estimated to be approximately equal to two-thirds of the total content in the copolymer.
