Abstract

Two grades of a novel biodegradable copolymer of -pentadecalactone (PDL) and 2-oxo-12-crown-4 (OC), with respective molar compositions of 77/23 and 52/48, were characterized with 1D and 2D MAS 1H and 13C NMR spectroscopy. The results indicate that both copolymers are semi-crystalline with PDL divided over the crystalline and amorphous phase, and OC exclusively located in the amorphous phase. Proton T2 and T1 relaxation confirm the existence of small crystalline domains.
