Abstract
A poly(non-conjugated diene) based sunscreen has a plurality of repeating units where each repeating unit has at least one UV absorbing chromophore that is situated between and connected by chains to two mono-ene units where each UV absorbing chromophore absorb UVA and UVB light. The poly(non-conjugated diene) based sunscreen can be included with a vehicle for application to the skin to prevent sunburn. The poly(non-conjugated diene) based sunscreen can be prepared by acyclic diene metathesis polymerization.
