以甲基丙烯酰氯为原料，采用迭代延伸法合成了3种含1、2和3个全氟环丁基（PFCB）芳醚基团的甲基丙烯酸酯单体。随后，这些甲基丙烯酸酯单体通过常规的自由基聚合在溶液中使用AIBN作为引发剂进行聚合，以提供一系列具有优异溶解性的聚甲基丙烯酸酯均聚物，其重复单元包含一个、两个或三个PFCB芳基醚部分。通过紫外维斯光谱和静态水接触角测试，研究了PFCB芳醚单元数目对聚甲基丙烯酸酯透光率和表面润湿性的影响。结果表明，这些含PFCB芳醚结构的聚甲基丙烯酸酯具有高的透明性和强的疏水性。从热重分析的结果还发现，所得的包含两个和三个PFCB芳基醚部分的半氟化聚甲基丙烯酸酯的初始分解温度接近350 °C，这远高于常见的聚（甲基丙烯酸甲酯）的初始分解温度，这表明在PFCB芳基醚部分存在下半氟化聚甲基丙烯酸酯具有更高的热稳定性。
Three fluorine-containing methacrylate monomers consisting of one, two and three perfluorocyclobutyl (PFCB) aryl ether moieties were designed and synthesized through the esterification reaction between methacryloyl chloride and corresponding intermediates bearing different numbers of PFCB aryl ether moieties, which were achieved via an iterative elongation methodology. Subsequently, these methacrylate monomers were polymerized via conventional free radical polymerization in solution using AIBN as initiator to provide a series of polymethacrylate homopolymers with excellent solubility, whose repeat units contain one, two or three PFCB aryl ether moieties. The influence of the number of PFCB aryl ether moiety in each repeat unit on the light transmittance and surface wettability of the corresponding polymethacrylates were investigated by UV/vis spectroscopy and static water contact angle test. The results indicated that these polymethacrylates containing PFCB aryl ether moieties exhibit high transparency and strong hydrophobicity. It was also found from the results of thermogravimetry analysis that the initial decomposition temperatures of the resulting semi-fluorinated polymethacrylates comprising two and three PFCB aryl ether moieties are approaching 350 °C, which is much higher than that of common poly(methyl methacrylate), indicative of higher thermal stability of semi-fluorinated polymethacrylates in the presence of PFCB aryl ether moieties.
