A Green Pathway to Adjust the Mechanical Properties and Degradation Rate of PCL by Blending Bio-sourced Poly (Glycerol-Succinate) Oligoesters

Abstract

Fully bio-sourced oligoester based on poly (glycerol-succinate) (PGS) with controllable sizes and topologies were prepared by melt phase polycondensation. The oligoester was further used to modify Poly (ε-caprolactone) (PCL) by blending method at a mild processing procedure. As it can be observed, the PGS modifier was well dispersed in the PCL matrix. The PGS can influence the crystallization and significantly accelerate the degradation of PCL matrix. There is no significant decrease of mechanical properties after the blending modification. Notably, the method here is quite convenient and solvent-free, by which we can achieve the PCL modification at a very mild situation. Therefore, the work here is an effective, sustainable and environmental friendly modifying method for PCL to accelerate the degradation rate.
