摘要
本文用红外光谱法评价降解聚丙烯ＰＰ薄膜的光降解性。其研究结果表明，芳香酮类光敏剂与钴或铁络合物光敏剂协同使用，比前者单独使用，具有更好的自氧化或光氧化降解作用。在红外光谱１７１０ｃｍ－１和３４００ｃｍ－１附近出现明显多重缔合羰基和羟基宽峰，表明其氧化降解主要生成羧酸类和过氧化羰基类等含氧产物。
In this paper,the photodegradation of degradable polypropylene film was evaluated with infrared spectrometry.The results showed that synergistic combination of aromatic ketones with Co or Fe complexes has better auto-oxidative or photo-oxidative degradation than the individual use of aromatic ketones.Around 1710cm-1 and 3400cm-1 in infrared spectrum,clearly-appeared multi-concluded broad peaks of carbonyl and hydroxyl group showed that oxygen-containing products such as carboxylic acids and peroxy carbonyl groups were formed mainly in the oxidative degradation.
