Compatibility and Accelerated Degradation of L-Tyrosine Derived Biodegradable Polycarbonate/PEG Blends

Abstract:

In the present study, the compatibility and degradability of L-tyrosine derived polycarbonate(PC)/Poly(ethylene glycol) blend were investigated. The PC was synthesized in our laboratory. Blends of the polymers with compositions 95/5, 85/15, 75/25,50/50 and 25/75 w/w were prepared by solution-casting. The blends were characterized by FT-IR,DSC,XRD,SEM. No obvious two phases were observed. Analysis of water absorption revealed that the combination of PC and PEG improved the hydrophilicity of PC. DSC and SEM analysis implied that all those components in consideration were compatible well in the blend formulation systems.Tg of the blends decreased with increasing PEG content. With the increase of the soft segment PEG content, the water retention ratio increases from 37% to 83%.
