摘要

Abstract

A carbon dioxide copolymer poly(urethane-amine) (PUA) was blended with poly(propylene carbonate) (PPC) in order to improve the toughness and flexibility of PPC without sacrificing other mechanical properties. Compared with pure PPC

the PPC/PUA blend with 5 wt% PUA loading showed a 400% increase in elongation at break

whilst the corresponding yielding strength remained as high as 33.5 MPa and Young’s modulus showed slightly decrease. The intermolecular hydrogen bonding interaction in PPC/PUA blends was comfirmed by FTIR

2D IR and XPS spectra analysis

and finely dispersed particulate structure of PUA in PPC was observed in the SEM images

which provided good evidence for the toughening mechanism of PPC.
