Structural and Thermal Characterization of Castor Oil Based Unsaturated Polyester Resin

Abstract

In the present study, unsaturated polyester resins based on castor oil was synthesized. Structure elucidation of the synthesized unsaturated polyester resin was done by FTIR and 1H NMR spectroscopy. Thermogravimetric analysis was used to evaluate the thermal stability of cured unsaturated polyester resin. Thermogram plot was further utilized to calculate various other parameters such as statistic heat-resistant index (Ts) and the integral procedural decomposition temperature (IPDT). Comparable properties with respect to commercial resins were reported for the synthesized polymers

A new type of unsaturated polyester resin with epoxy functionalized nano‐silica and dimer fatty acid: Preparation and property

“…Due to the low toughness, poor thermal stability, and poor aging resistance of UPR, UPR usually needs to be modified for better comprehensive properties 6–9 . The most common method is to add functional fillers in UPR, such as nanoparticles, 10–12 fibers, 13–16 elastomer, 17,18 and vegetable oil 19–21 . He et al 22 studied the effect of primary particle size and aggregate particle size of MgO on the toughening of UPR.…”
