摘要：

Compression-moulded sheets of bacterially produced poly(beta-hydroxybutyrate) (PHB) blended with synthetic poly(epsilon-caprolactone) (PCL) were investigated over the complete composition range from pure PHB to pure PCL. These blends are of potential interest because both components are biodegradable. Although PHB and PCL are immiscible, they formed mechanicaly compatible films containing phase-separated partially crystalline domains. The mechanical properties varied considerably with composition. The low melting point of PCL (approximately 60-degrees-C) prevented temperature-resistant blends from being obtained for compositions containing less than 60% PHB.
