A novel, simple, and cheap method to synthesize antioxidant methacrylic-ferulic acid copolymer (PMAA-FA) by free radical polymerization was developed by employing a hydrogen peroxide-ascorbic acid pair to produce hydroxyl radicals acting as radical initiators. FT-IR spectra were performed to verify the insertion of ferulic acid into the polymeric chain, and the antioxidant activity of PMAA-FA was compared to that of a control polymer synthesized in the absence of antioxidant molecule. Good antioxidant activity was demonstrated by obtained materials, showing the efficiency of the polymerization method. This material could be useful in the pharmaceutical field and in the food industry (food packaging).
通过使用过氧化氢-抗坏血酸对产生作为自由基引发剂的羟基自由基，开发了一种新颖、简单且廉价的通过自由基聚合合成抗氧化剂甲基丙烯酸-阿魏酸共聚物（PMAA-FA）的方法。进行了傅里叶变换红外光谱（FT-IR）以验证阿魏酸插入聚合物链中，并将PMAA-FA的抗氧化活性与在没有抗氧化剂分子的情况下合成的对照聚合物的抗氧化活性进行了比较。所获得的材料显示出良好的抗氧化活性，表明了聚合方法的有效性。这种材料可用于制药领域和食品工业（食品包装）。
