Abstract
A novel pathway for the synthesis of poly(propylene fumarate) includes first producing bis-hydroxypropyl fumarate and then its transesterification into poly(propylene fumarate). This synthetic pathway permits production of high molecular weight poly(propylene fumarate) and enables the production of a composite material useful in orthopedic procedures.
