[en] Polylactides are widely investigated as materials for tissue engineering. However characteristics such as low flexibility and elongation before fracture can be improved by trimethylene carbonate (TMC) addition to lactic acid copolymer (PLDLA). The objective of this work was to synthesize and characterize the terpolymer of L-lactic acid, D,L-lactic acid and TMC. Thus, the terpolymer was synthesized with 20 and 30% of TMC as confirmed by FTIR and 1H and ¹³C NMR. The GPC analysis showed that the terpolymers had average molar weight (Mw) in the order of 105 g/mol, an important feature that allows the attainment of minimum mechanical properties for structural applications. The thermal investigation of material showed a slight decrease of Tg comparing to PLDLA. Furthermore, the one step degradation of the terpolymer was initiated around 290 deg C, as seen by TGA. These results shows that it was possible to produce a terpolymer from L-lactide, D,L-lactide and trimethylene carbonate. (author)
