DOIAbstract
Fatty acid based precursors were synthesized by a one-step reaction from oleic or lauric acids and glycidyl methacrylate to be used later in polymer formulations. Different times of reaction, amounts of catalyst and initial ratios of reactants were evaluated, obtaining conversions higher than 0.9 for the best conditions. The monomers obtained are interesting alternatives to synthetics since they combine low cost with environmental advantages (i.e. higher bio-carbon content). These polymeric precursors were reacted separately in cationic and free radical polymerizations with styrene (50 wt%) to evaluate their potential as greener monomers. The lauric acid precursor and free radical polymerization were the alternatives that produced elastomer...
