Abstract

Polyurethanes (PUs) produced by the polycondensation reaction of polyols and diisocyanates are an important class of polymers with a wide variety of applications. Traditionally, these materials are derived from petroleum feedstocks. Presently, vegetable oils are attracting attention as an alternative to petroleum for the development of bio-based polyols and PUs. To mitigate the inherent limitations of the triacylglycerol (TAG) structures of the natural oil in PUs, new strategies have been developed for the transformation of the natural feedstocks. Olefin metathesis is a versatile and powerful modification approach used on vegetable oil to produce fine chemicals and novel metathesized triacylglycerol (MTAG) structures including TAG-like structures with terminal functionality and oligomers of TAGs. The present article reports on the recent development in the application of the product of metathesis-modified natural oils for the preparation of polyols and PUs. It focuses on the role of the unique structures of the polyols obtained from MTAG on the final PU properties.
