- This paper presents results of degradation process investigations of resorbable poly(lactide-trimethylene carbonate). Materials used in this work were synthesized by the ring opening polymerization. Polymerization was carried out in bulk using Zr(acac)4 as initiator. The resulting copolymers were characterized by high resolution NMR spectroscopy. Then the copolymers were allowed to degrade in H2O for 53 weeks. These conditions allowed to analyze the degradation products of poly(lactide-trimethylene carbonate) and to determine the structure of oligomers using multi-stage mass spectrometry technique (ESI-MSn). ESI-MS analysis revealed the presence of two kinds of oligomers.
