DSC, WAXD and SEM studies of biodegradation of poly(l-lactide–glycolide–trimethylene carbonate) shape memory terpolymer

Presented study is a part of structural project devoted to elaborating the basis of manufacturing technology of l -lactide–glycolide–trimethylene carbonate polymer system—a novel full biodegradable and resorbable shape–memory polymers. In this paper we took an attempt to describe the transformation of structure of studied shape–memory terpolymers under the influence of the process of biodegradation that occurred in time of implantation samples using first of all the differential scanning calorimetry and supplementary—the wide angle X-ray diffraction and scanning electron microscopy methods. After a 5-year-period of ageing the distinct increase of crystallinity of fibres was found.
