In one or more embodiments, the present invention is directed to poly(propylene fumarate) polymers and polymer structures made therefrom (and related methods) that have been end and/or monomer functionalized to add functional groups for post-polymerization modification with bioactive materials or other functional species, preferably through one of many facile click reactions. In some embodiments, end-group functionalization is accomplished via a functionalized initiating alcohol used during polymerization. In some embodiments, functionalization of these poly(propylene fumarate) polymers is accomplished via the functionalization of the propylene oxide monomer precursors, which then form functionalized side-chains on the resulting poly(propylene fumarate) polymers.

The present invention is directed to a series of polymers containing end groups that are absorb ultraviolet (UV) light. The invention is also to the use of such compounds in the cosmetic, toiletry and personal care areas. These polymers can be utilized to produce films and provide solvent properties for the formulation of for ultra-violet absorbing formulations (like sunscreens) and provide outstanding dispensability and anti-agglomeration properties for inorganic sunscreens containing ZnO and TiO.sub.2. The ability to provide uniform non agglomerating sun care formulations results in formulations with increase SPF values and improved water-resistant properties in cosmetic formulation. The compounds of the present invention by themselves do not have ultra violet absorption at the particular wavelength that contributes to sun protection and consequently are not themselves sunscreens.
