Abstract
Aspects of the present invention relate to polymers, and particularly to farnesene polymers functionalized with one or more oxirane groups and, optionally, one or more hydroxyl groups. According to one aspect of the invention, provided is an epoxidized and optionally hydroxyl-functionalized polyfarnesene. The epoxidized farnesene polymer has at least one of a side chain or a main backbone functionalized with at least one oxirane group and, optionally, at least one terminal end functionalized with a hydroxyl group. In accordance with another aspect of the invention, a method is provided for preparing an epoxidized and optionally hydroxyl-functionalized polyfarnesene. The method includes epoxidizing a farnesene polymer, which may optionally contain one or more terminal hydroxyl groups, to functionalize at least one of a side chain or a main backbone of the farnesene polymer with an oxirane group.
