Researchers from Japan performed an experiment to analyze the change in characteristics of PLLA by introducing a biobased branched polymer bearing castor oil core as a nucleating agent. The Biobased polymer bearing castor oi
l core was synthesized. The nucleating effect of the branched polymer on the crystallization of PLLA was analyzed using differential scanning calorimetry and a polarized optical microscopy.
Results showed that by the addition of the branched polymer, the spherulite size of PLLA became smaller and the strain at break of PLLA containing the branched polymer was improved.
Researchers from Malaysia performed an experiment to optimize the solvent extraction of castor oil through response surface methodology. Castor oil was extracted using solvent extraction with three different solvents: hexane, petroleum-ether and ethanol. Optimization of the percentage of oil yield was carried out using response surface methodology and Box-Behnken design.
Scientists from India conducted an experiment to analyze the suitable source needed to manufacture UV-curable polyurethane dispersions for coating applications. They synthesized a series of novel waterborne UV-curable polyurethane dispersions from castor oil, Isophorone diisocyanate (IPDI), Dimethylolpropionic Acid (DMPA)and Hydroxyethylmethacrylate (HEMA) by acetone process.
und assisted biodiesel synthesis from castor oil using response surface methodology. Parameters such as reaction time, methanol to oil molar ratio, ultrasonic cycle and ultrasonic amplitude were taken into consideration to optimize the biodiesel synthesis process.
ucture was determined.
