Scientists from Malaysia performed an experiment to compare the physico-chemical properties of high performance polyurethane prepared using pure poly propylene glycol (PPG) and that prepared from PPG and castor oil.
Characterization studies indicated the presence of large -CH stretching in castor oil mixed polyurethane with larger oxidative thermal stability over pure PPG polyurethane. The tensile properties were found to be almost comparable showing that mixed polymers can be used in future to overcome environmental and economic crisis.
