Abstract

In this work, polymeric derivative of ferulic acidwas synthesized by employing ascorbic acid-H2O2 asredox initiator system at room temperature. The insertionof ferulic acid into the polymeric chain was confirmed byFT-IR analyses, and the total antioxidant capacity of themacromolecular system determined by the molybdatemethod, and correspond to a ferulic acid equivalentconcentration of 0.59 mM. UV spectra are characterized bybroad absorption bands in the UVA and UVB region, showingthe efficiency of the polymeric system in preventing theUV-induced damages.
