Scientists from Japan conducted an experiment to analyze the nature and 
characteristics of polymerizable vesicles produced by using oxyethylene hydrogenated castor oil. Polymerized vesicles were produced in aqueous solution. Hydrogen NMR spectroscopy was used to investigate the polymerization process using azobis(isobutyronitrile) as an initiator.
Results showed that the polymerized vesicles were resistant to disruption by polyoxyethylene(10) octylphenyl ether. The degree of resistance depends on vesicle concentration and incubation temperature and this dependence is due to the inter-vesicle polymerization.
Researchers from India conducted an experiment to analyze the thermo-mechanical properties of castor oil based polyol foam. Castor oil was extracted usi
ng hydraulic press and was allowed to react with toluene diisocyanate and other material to obtain the polyurethane foam. Incorporation of castor oil increased the hardness, density and compression of the foam. The cost of production also significantly decreased.
These results suggest that castor oil could be widely used for the manufacture of polyurethane foam.

Scientists from India conducted an experiment to determine the kinet
ics of the production of biodiesel. Transesterification of castor oil was carried out with methanol and sulphuric acid as catalyst under different temperature conditions.
The obtained results were analyzed with respect to three types of reaction kinetics and it was concluded that the experimental data followed second-order reversible reaction kinetics.
Researchers from Malaysia conducted an experiment to analyze the application of castor oil based polyurethane as a host in polymer electrolyte for electrochemical devices. The synthesized castor oil polyurethane was added with lithium iodide and sodium iodide in different wt% to form a film of polymer electrolytes.
The results showed that castor oil based polyurethane polymer electrolytes can be used as an alternative membrane for electrochemical devices.

Researchers from Spain conducted an experiment to compare conventional and ultrasound-assisted transesterification for the production of biodiesel from castoroil. The results showed that sonicated transesterification leads to higher castoroil methyl ester yield.
The energy required along each type of transesterification was measured which showed that sonicated transesterification consumes lower amount of energy than conventional one.
Scientists from Korea have conducted an experiment to test the effects of castor oil/ polycaprolactone hybrid polyols on the properties of biopolyurethane. Organic solvent soluble castor oil/polycaprolactone diol (PCL) based polyurethane was prepared.
The results showed that the tensile properties and shape memory of castor oil/PCL based polyurethane were enhanced when compared with PCL based polyurethane. The enhancement in properties was due to the increased hard segment portion and cross linking density by 3 urethane bonds formed per molecule in the castor oil/PCL mixed system.
This research suggests that castor oil/ PCL based polyurethane could be used as biobased coating materials.
