Polymers are typically produced from crude oil which is a non-renewable resource. With the fast depletion of the petroleum resources, the development of materials based on renewable resources is becoming important. Polymers prepared from renewable resources are under development, but has mainly focused on thermoplastic polymers such as polylactic acid. For some applications, such as composites and coatings, thermoset polymers are often preferred. Consequently, it is important to develop thermoset resins from renewable resources as well. Plant oils, such as soybean oil and linseed oil, have been utilized by mankind for a long time. Soybean oil is produced in large quantities and soybean oil is an excellent starting material for the synthesis of thermoset resins. A possible strategy to prepare thermoset resins from plant oils is to introduce pendant methacrylate groups in the structure. Thus, the resins can be cured by a free radical polymerization. Such a resin is very susceptible to photopolymerization when exposed to ultraviolet (UV) radiation, which is a common technique to cure coatings. In the present study, three different thermoset resins were studied. Two of the resins were based on soybean oil while the third resin was based on lactic acid. The latter resin was prepared by a direct condensation of lactic acid and pentaerythritol and was finally end-capped with methacrylate groups. Several authors have studied the addition of nano-reinforcements to thermoset resins. One of the most promising nano-reinforcements is layered silicate which has shown to improve several properties. Layered silicate has been used to reinforce conventional resins with good results. The addition of layered silicates to the biobased resins can be used to improve the properties and to broaden the applications. The resins used in this study were therefore reinforced with layered silicate and UV-cured. The cured resins were characterized by Soxhlet extraction, photo-FTIR, DMTA and tensile tests which will be presented during the presentation.
