Abstract

A bio-based route to the production of trans-�²-farnesene has recently been commercialized. Trans-�²-farnesene is capable of being polymerized by both anionic and cationic pathways, creating low molecular weight polymers with structure-property relationships unique within the diene class of monomers. Trans-�²-farnesene is produced through fermentation of sugar feedstocks. The pathway offers an alternative to petroleum-based feedstocks derived from cracking processes. Anionic polymerization of the monomer produces a highly branched "bottle-brush" structure, with rheological and thermal properties that are markedly different than those of traditional linear diene polymers. Specifically, a lack of entanglements is observed even at relatively high molar masses. The synthesis and characterization of trans-�²-farnesene-based polymers will be presented, including anionically prepared low molecular weight diols and monols. Their utility as novel polyols in various end-use applications such as prepolymers for polyurethane synthesis will be reviewed.
