    Abstract

    Acrylate and methacylate monomers were obtained by reacting vernonia oil, a naturally epoxidized oil, with acrylic or methacrylic acid. The highest conversion (85-98%) of epoxy groups was obtained when the reaction was performed with an excess of the carboxylic acid at 100-120°C. The acrylate and methacrylate monomers of vernonia oil were characterized by IR and NMR spectroscopy. These monomers were then cured by sunlight in the presence of benzophenone to produce transparent films. In addition, interpenetrating polymer networks (IPNs) were prepared in a two-step technique from the sunlight-cured methacrylate of vernonia oil, as the elastomeric component, in combination with a cured epoxy resin (a bisphenol A-type resin). Dynamic mechanical analysis showed good compatibility between the networks of the two cured polymers. An IPN with a 1:1 composition of the two polymer components exhibited the properties of a reinforced elastomer.
