Abstract: Self-transesterification of castor oil was employed to prepare higher molar mass polyols possessing interesting properties. Structure of the polyols is however, complex resulting from reversible nature of transesterification reaction that involves formation and destruction of new polyols simultaneously. Detail structure of thus prepared polyols was studied using spectrometric analysis including MALDI-TOF. Polyurethane elastomers prepared from these polyols provided soft material with low Shore A hardness. These polyols were also tested in molded polyurethane foams and their polyurethane properties were compared with that of the commercial bio-polyols.
