Abstract

A terminal hydroxyl functionalized polyfarnesene is provided. The polyfarnesene has more than two terminal hydroxyl groups per molecule, on average, based on the number average molecular weight. The polyfarnesenes may be homopolymers or copolymers of farnesene. Also provided is a method of making these polyfarnesenes having more than two hydroxyl groups per molecule. A composition for making a polyurethane comprising a diisocyanate and the terminal hydroxyl functionalized polyfarnesene is also provided.
