Abstract A method to produce poly hydroxybutyrate(PHB) by bulk polymerization of 3-hydroxybutyrate was put forward.An experimental device was designed to produce PHB and the condition of reaction was confirmed.The results indicated the molecular weight of product increased gradually while the pressure decreased and the reaction time prolonged within the definite scope of reaction time.The biodegradations of PHB made by both chemical synthesis and fermentation were analyzed.Pseudomonas spp. was found to be the main microbe degrading PHB and the PHB synthesized chemically can be degraded completely by the microbe in soil.
