摘要：

The major physical properties of poly(hydroxybutyrate) (PHB) and its copolymers with hydroxyvalerate (PHB/HV) and those of their blends are summarised. Cases of liquid-liquid phase separation in homopolymer copolymer blends are reported and conditions where further phase separation occurs during crystallisation are documented. The crystallinity and degree of comonomer inclusion in the crystallisation of copolymers are described and quantified. It is argued that the mechanism for the inclusion of comonomer units in the crystals is of a kinetic rather than an equilibrium nature.
