【 摘 要 】

Poly(hydroxybutyrate)and its copolymers are linear polyesters behaving as conventional thermoplasticmaterials. However, they are totally biodegradable and produced by a wide varietyof bacteria from renewable sources. Some properties and high production cost arestill preventing future applications. In an attempt to improve the propertiesand to reduce cost blending PHB with others polymeric materials is one of themost efficient method. In this paper, miscibility, compatibility, morphologicaland mechanical aspects of PHB blends will be reviewed. An extensive revision overtwenty last years was realized about works of blends based on PHB and its copolymers.
