Miscibility, Morphology and Crystallization Behavior of Poly(Butylene Succinate-co-Butylene Adipate)/Poly(Vinyl Phenol)/Poly(l-Lactic Acid) Blends
Amorphous poly(vinyl phenol) (PVPh) is introduced into poly(butylene succinate-cobutylene adipate)/poly(L-lactic acid) (PBSA/PLLA) blends via solution casting. Fourier transform infrared spectroscopy (FTIR) analysis verifies that intermolecular hydrogen bonding formed in PBSA/PVPh/PLLA blends. The miscibility between PBSA and PLLA is improved with PVPh incorporation as evidenced by approaching ...
متن کاملTesting, characterization and modelling of mechanical behaviour of poly (lactic-acid) and poly (butylene succinate) blends
Background: Significant amount of research, both experimental and numerical, has been conducted to study the mechanical behaviour of biodegradable polymer PL(L)A due to its wide range of applications. However, mechanical brittleness or poor elongation of PL(L)A has limited its applications considerably, particularly in the biomedical field. This study aims to study the potential in improving th...
متن کاملToughening of biodegradable polylactide/poly(butylene succinate-co-adipate) blends via in situ reactive compatibilization.
Polylactide and poly(butylene succinate-co-adipate) (PLA/PBSA) were melt-blended in the presence of triphenyl phosphite (TPP). An increase in the torque during melt mixing was used to monitor the changes in viscosity as compatibilization of the blends occurred. Scanning electron micrographs showed not only a reduction in the dispersed-phase size with increased TPP content but also fibrillated l...
متن کاملPerformance of biodegradable microcapsules of poly(butylene succinate), poly(butylene succinate-co-adipate) and poly(butylene terephthalate-co-adipate) as drug encapsulation systems.
Poly(butylene succinate) (PBSu), poly(butylene succinate-co-adipate) (PBSA) and poly(butylene terephthalate-co-adipate) (PBTA) microcapsules were prepared by the double emulsion/solvent evaporation method. The effect of polymer and poly(vinyl alcohol) (PVA) concentration on the microcapsule morphologies, drug encapsulation efficiency (EE) and drug loading (DL) of bovine serum albumin (BSA) and ...
متن کاملCrystallization behaviour of cellulose acetate butylate/poly(butylene succinate)-co-(butylene carbonate) blends
The kinetics of the isothermal crystallization process from the melt of pure poly(butylene succinate)-co-(butylene carbonate) (PBS-co-BC) and its blends with cellulose acetate butylate (CAB) (10–30 wt%) was studied by differential scanning calorimetry (DSC) and the well-known Avrami equation. In the blends, the overall crystallization rate of PBS-co-BC became slower with increasing CAB content....
