Hydrolytic and enzymatic degradation of liquid-crystalline aromatic/aliphatic copolyesters.
Aromatic/aliphatic copolyesters containing hydrophilic moieties in the main chain or side chain were synthesized by bulk polycondensation of aromatic monomers without or with solubilizing substituents and aliphatic monomers. Hydrolytic and enzymatic degradation studies were carried out in vitro at 37 degrees C in pH 7.4 phosphate buffer and in Tris-HCl buffer containing proteinase K. The result...
متن کاملEnzymatic degradation of Poly (ε-Caprolactone) and Starch blends bontaining SiO2 nanoparticle by Amyloglucosidase and α-Amylase
The aims of the study were to investigate the effect of poly(ε -caprolactone) (PCL) and nano- SiO2 within the thermoplastic starch (TPS) blends on the rate and extent of starch enzymatic hydrolysis using enzymes α-amylase and amyloglucosidase. The results of this study have revealed that blends with nano-SiO2 content at 6 wt% exhibited a significantly reduced rate and exte...

متن کاملHydrolytic degradation of poly(ε-caprolactone) with different end groups and poly(ε-caprolactone-co-γ-butyrolactone). Characterization and kinetics of hydrocortisone delivery
Asymmetric telechelic α-hydroxyl-ω-(carboxylic acid)-poly(ε-caprolactone) (HA-PCL), α-hydroxyl-ω-(benzylic ester)-poly(ε-caprolactone) (HBz-PCL) and an asymmetric telechelic copolymer α-hydroxyl-ω-(carboxylic acid)-poly(ε-caprolactone-co-γbutyrolactone) (HA-PCB) were synthesized by ring-opening polymerization of εcaprolactone (CL). CL and CL/γ-butyrolactone mixture were used to obtain homopolym...
