| description | The hydrolytic degradation of poly-b-(hydroxybutyrate) PHB, poly-b-
(hydroxybutyrate-co-b-valerate) (PHBV) and PHBV/cellulose triacetate blend was
sutnuddeire dd ifferent pH at 37 °C. PHBV showed a similar trend of degradation to PHB but at
rhaitgehse irn alkaline medium. The presence of cellulose triacetate in the blend increased the
water uptake and permeability which favoured the hydrolytic degradation especially in
lpoHw mere dium. In the surface hydrolysis of PHB and its blends, the overall degradation rate was
increased with higher pH values. The melting temperature, crystallinity and tensile properties
were also determined. The blend, PHBV/CTAc had the lowest crystallinity values and
hPaHdB t he highest. However, the blends were mechanically better in strength and
toughness |
