Abstract

Vegetable oils and their derivatives have been widely used for the production of various polymers including polyols and polyurethanes. Vegetable oil derivatives, such as fatty acids, fatty acid esters, and crude glycerol, can be obtained via hydrolysis or transesterification of vegetable oils. Polyols and polyurethanes with properties comparable to those of petroleum-based analogs have been prepared from vegetable oils and their derivatives for various applications such as foams, coatings, adhesives, etc. This chapter reviews the structures and compositions of vegetable oils and their derivatives, synthetic methods of producing polyols from vegetable oils and their derivatives, properties of these polyols, and performance and applications of the resulting polyurethanes.
