本文以丙烯酸2，2，3，4，4，4-六氟丁酯（F6 BA）为原料，通过溶液聚合法合成了一系列含不同氟基团的PSA。与现有的PSA相比，氟化丙烯酸PSA在对低表面能材料的吸附方面表现出优异的性能。F6 BA对PSA的耐热性起到了积极的作用，这主要是由于氟化基团的加入提高了PSA的分解温度。红外光谱和差示扫描量热分析结果表明，含氟基团成功地引入到共聚物结构中，所有单体均发生了较好的共聚反应。此外，还证实了氟的引入有效地改善了PSA的润湿性，并扩展了PSA对水腐蚀的保护性能。(C)2015爱思唯尔B. V.保留所有权利。
In this work, a series of PSAs with various fluorinated groups were synthesized using 2,2,3,4,4,4-hexafluorobutyl acrylate (F6BA) via solution polymerization. Compared to existing PSAs, fluorinated acrylic PSAs exhibited excellent performance in terms of the adhesiveness to the low surface energy materials. F6BA played a positive role in heat resistance of PSAs, resulting from the improvement of decomposition temperatures of PSAs substantially due to the addition of fluorinated groups. FT-IR and DSC results indicated that fluorinated groups were introduced to the structure of copolymer successfully and all the monomers were well copolymerized. Furthermore, it was confirmed that the incorporation of fluorine improved wettability of PSAs effectively and extended protective property of PSAs against the water corrosion. (C) 2015 Elsevier B.V.
