20080293894 | METHOD OF IMPROVING THERMAL STABILITY OF POLY-3-HYDROXYBUTYRATE - The present invention discloses a method of improving the thermal stability of poly-3-hydroxybutyrate (PHB). The thermal stability of PHB was improved by grafting maleic anhydride (MA) onto the PHB through various processes. It has been proved that purified grafted PHB had a higher degradation temperature, a better thermal stability than the pristine PHB, and was not easy to decrease molecular weight by heat treatment. At the same time, the crystallization rate, the melting temperature and crystallinity were all increased. The MA was effectively grafted onto PHB by processes of solution grafting, melt grafting, mechanical grafting methods and so on. The grafting degree of MA was changed with the increasing amounts of the initiator and MA. The degradation temperature of the PHB was significantly increased by MA grafting because the degradation was blocked in the formation of six-member ring by the steric hindrance of the grafted MA. The PHB grafted with the mechanical grafting method was not easy to generate scission degradation during reaction, and showed the best thermal stability and forming ability. The initial degradation temperature of PHB was increased at least 50° C. | 11-27-2008 |
