Abstract

The synthesis of new materials from vegetable oils has increased due to technological applications and low environmental impact. Oil obtained from the patau & aacute; fruit (Oenocarpus bataua) is rich in linoleic and oleic fatty acids that can be modified by their double bonds to obtain green monomers. Thus, patau & aacute; oil can be reacted with an intercrossing agent to obtain a thermosetting polymer. This work focused on developing biomass-derived materials with hardened mechanical properties based on epoxidized patau & aacute; oil and benzophenone dianhydride. The global approach used for the crosslinking process started with the choice of crosslinker and ammonium salts as catalysts. Furthermore, epoxide-dianhydride copolymerization was investigated at different molar ratios (of anhydride and catalyst) to adjust the parameters that led to better conversions and properties. The final material exhibited conversions > 97% using only 5% catalyst and 2 h of curing at 120 degrees C, with the degradation process starting at 240 degrees C and glass transition temperature (T-g) at -1.5 degrees C. The produced polymer is luminescent and has low water absorption, suggesting its application in electronic devices and insulation. (AU)
