Descripción
Due to advantageous features such as shorter reaction times, greater yields, limited generation of by-products and relatively easy scale-up without detrimental effects, microwave-assisted synthesis has become a very appealing tool in organic synthesis. On the other hand, its implementation in the context of the synthesis of biomaterials for biopharmaceutical applications has been more limited. The present work reports on the fast and efficient microwave-assisted synthesis of poly(ethylene glycol) (PEG)-initiated poly(epsilon-caprolactone) diols (PCL) by the ring-opening polymerization (ROP) of epsilon-caprolactone using stannous octanoate as the catalyst. Since the PEG content in the synthesized copolymers was extremely low (0.2-1.9%), products were highly hydrophobic and displayed the intrinsic physicochemical and thermal properties of pure PCL. As opposed to the more time–consuming conventional thermally-driven synthesis that usually demands 2-3 h, the microwave technique resulted in high molecular weight PCL derivatives within 10-15 min. The influence of different parameters affecting the synthetic process, namely monomer-to-initiator ratio, reaction time, catalyst concentration and the presence, type and concentration of solvent were thoroughly investigated.
