Biodegradable Poly(ester-urethane)s Containing Poly(butylene succinate) and Mesogen Segments

Abstract:

A series of biodegradable segmented poly (ester-urethane) s were prepared by solution polymerization of poly (butylene succinate) (PBS), mesogenic diol (MD), and hexamethylene diisocyanate (HDI). The MD content was varied from 0 to 40 mol% so that the effects of the mesogen content on the thermal and physical properties, and enzymatic degradation were examined respectively. It was found that introducing mesogen segments could increase the thermal stability and the elastic properties, while reduced the phase transition temperatures, the degree of relative crystallinity (Xc) and the enzymatic degradation rate.
