dc.description.abstract | The investigation is based upon recent research in the area of the synthesis of biodegradable poly(L-lactide) (PLLA) for biomedical applications using stannous octoate (SnOct) as an initiator. The objective was to investigate factors that affect the synthesis of poly(L-lactide), such as monomer purification, vacuum required for monomer drying, polymerization reacton time and catalyst concentration. Complete polymer characterization was done by 1H-NMR, IR spectroscopy and light scattering, in order to reveal the polymerization mechanism. An attempt was made to obtain a polymer of high molecular weight and good mechanical properties that could be used for the processing of biodegradable surgical sutures. Experiments showed that the optimum conditions to obtain polymer of high molecular weight (≈ 30 × 104) are: vacuum required for monomer drying (0.2 mmHg), purification of both monomer and polymer by recrystallization/precipitation, monomer/initiator mole ratio ([M]/[I] about 5000 and a polymerization time of approximately 50 h. | en |
