Synthesis and Thermal Characterization of Polyurethanes obtained from Linseed oil and Olive oil-based Polyols
J. Environ. Nanotechnol., Volume 8, No 4 (2019) pp. 12-16
Abstract
Using vegetable oils as a substitute for fossil feedstock have become a hot topic in polymer science. Vegetable oils are abundant, less-costly and renewable resources. The present study was aimed at creating bio-based polyols from linseed oil (Linum usitatissimum) and olive oil (Gossypium barbadanse). Polyurethanes obtained from bio-based polyols were synthesized with two different isocyanates, 4, 4′-methylene diphenyl diisocyanate and hexamethylene diisocyanate, for different polyol/isocyanate ratios; they were further characterized by Fourier-Transform Infrared Spectroscopy, Thermogravimetric analysis, Differential Scanning Calorimetry, and Scanning Electron Microscopy, concluding that Linum usitatissimum and Gossypium barbadanse could be considered as valid alternatives for the synthesis of bio-based polyols.
