The DSC curve showed that the solvents used to solve the polymer mixture cause changes in the thermal behavior of PET-R films and in PHBPET-R blends. SEM studies of the PHBPET-R blends show that with a gradual mass increase of PET-R, there are gradual increases in the porosity of the films.581-584engPolymerBiodegradationPolymeric blendPHBPETArtigo10.1007/s10973-009-0328-5WOS:000271108200035Acesso restrito747131011399914084983108918100820000-0002-7984-5908
