Nowadays, unsaturated polyester resins (UPR) are mainly obtained from non-renewable resources. The ever-increasing regulations and the continuous demand for more sustainability have led to extensive research towards more environmentally suitable alternatives to petroleum-based materials. However, one of the main disadvantages of bio-based UPR is their relatively high viscosity compared to petrochem. ones. In order to overcome this drawback, in this work, we investigated the possibility to lower the resin viscosity utilizing a mixture of di-Me itaconate (DMI) and Me methacrylate (MMA) as a reactive diluent. The effect of the DMI and MMA ratio on resin rheol. properties was investigated. The optimal curing parameters were determined and all UPRs had a high gel content, which was shown to be dependent on the DMI and MMA ratio in the formulation. Furthermore, thermomech. and mech. properties of the resulting network were also found to be affected by the used reactive diluent mixture A small substitution of DMI by MMA proved to be advantageous since it offers lower resin viscosity and improved mech. properties.
