Abstract

With the goal of obtaining renewable diols and polyols for polyurethane (PU) technology, the thiol–yne coupling reaction was applied to alkyne-derivatized fatty acids derived from naturally occurring oleic and 10-undecenoic acids. The resulting monomers were then polymerized with 4,4′-methylenebis(phenylisocyanate) to produce the corresponding PUs. The chemical structures and thermal and mechanical properties of the synthesized PUs have been evaluated by FTIR and NMR spectroscopy, DSC, TGA and tensile tests respectively. Moreover, the biocompatibilities of the synthesized PUs with human osteoblast-like cell line (MG63) have also been evaluated for tissue engineering purposes.
