研究了在真空吸附装置上进行的气相化学衍生反应。用模型聚合物评价了三氟乙酸酐（TFAA）和肼的反应活性和选择性。结果表明，TFAA是羟基的良好衍生试剂，而肼不适合羰基的衍生试剂。用TFAA对火焰处理过的聚丙烯表面进行化学衍生分析表明，在各种火焰条件下，火焰处理引入的氧以羟基的形式存在的比例近似恒定（约20%）。通过衍生化选择性去除OH基团对火焰处理聚丙烯表面与反应性聚氨酯涂料的附着力有很大影响，这是界面发生化学反应的证据。
Vapour-phase chemical derivatisation carried out on a vacuum adsorption rig has been investigated. Model polymers were used to evaluate the reactivity and selectivity of trifluoroacetic anhydride (TFAA) and hydrazine. Results have shown that TFAA is a good derivatising reagent for hydroxyl groups, while hydrazine is not suitable for carbonyl groups. Chemical derivatisation with TFAA of flame-treated polypropylene surfaces has shown that under various flame conditions an aoproximately constant proportion (ca. 20%) of the oxygen introduced by flame treatment was present as hydroxyl groups. Selective removal of OH groups by derivatisation has a large effect on the adhesion of a flame-treated polypropylene surface to a reactive polyurethane paint, evidence of chemical reaction at the interface.
