Glass transition, melting, and crystallization temperature, obtained from DSC curves, and thermal degradation temperatures obtained from TG ones, were employed to evaluate the influence of the MA proportion on the modification in the PHB chain. According to the results, most of chain modification reactions are the 80/20 and 90/10 proportions. Observations suggest that most chain modification reactions occur when the ratio of PHB/MA is 80/20 or 90/10. This suggests that modifications of PHB in the presence of MA involve main chain scission.453-458engTransesterification reactionPoly(3-hydroxybutyrate)Maleic anhydrideArtigo10.1007/s10973-011-1706-3WOS:000296065100023Acesso restrito747131011399914084983108918100820000-0002-7984-5908
