Rosin is an abundant, hydrocarbon rich renewable resource obtained from pine trees. Several rosin-containing polymers were prepared with the aid of a number of controlled polymerization techniques. These polymers can be divided into two categories: non-degradable polymers and degradable polymers.1-5 The non-degradable polymers were prepared by atom transfer radical polymerization (ATRP), while the degradable polymers were prepared by either ring-opening polymerization or acyclic diene metathesis polymerization (ADMET). The attachment of the rosin moiety onto the polymeric framework led to an increase in the thermal properties of the polymers when compared to their un-substituted counterparts. The use of bi-functional initiators and the retention of end group functionality have led to the production of several novel polymers and have expanded the use of rosin based materials.
