- Abstract:
- Oligomeric polyether polyols were obtained through the acid-catalyzed
ring-opening polymerization of epoxidized methyl oleate and the subsequent
partial reduction of ester groups to give primary alcohols. The oligomers were
characterized with titration, spectroscopic techniques (Fourier transform
infrared and nuclear magnetic resonance), matrix-assisted laser
desorption/ionization time-of-flight mass spectrometry, size exclusion
chromatography, and differential scanning calorimetry. Depending on the degree
of reduction, polyols of different hydroxyl content values were obtained and
were reacted with 4,40-methylenebis(phenyl isocyanate) to yield polyurethanes.
These materials, which were characterized by differential scanning
calorimetry, thermogravimetric analysis, and dynamic mechanical thermal
analysis, could behave as hard rubbers or rigid plastics.
