摘要： Compositions and methods are described for polyurethanes with mechanical properties rivalling that of the highest performing commercially available elastomer materials by employing copolymers of a poly(farnesene) diol and ε-caprolactone as the polyol component. Poly(farnesene) diols are produced from biobased monomers and such copolymerization allows incorporation of renewable material in high performance polyurethane materials.
