Abstract
Provided herein are graft copolymers of polyfarnesenes with condensation polymers; and methods of making and using the graft copolymers disclosed herein. In certain embodiments, the condensation polymers include polyesters, polycarbonates, polyamides, polyethers, phenol-formaldehyde resins, urea-formaldehyde resins, melamine-formaldehyde resins and combinations thereof. In some embodiments, the polyfarnesenes include farnesene homopolymers derived from a farnesene, and farnesene interpolymers derived from a farnesene and at least a vinyl monomer. In certain embodiments, the farnesene is prepared from a sugar by using a microorganism.
