New perfluoropolyalkylether (PFPAE) monomers, chain extended with different alkyl groups and functionalized with vinyl ether or epoxide end-groups, were employed, together with trimethylolpropane trivinyl ether or trimethylolpropane triglycidyl ether, to produce fluorinated copolymers. The photoinduced cationic polymerization was investigated, and the PFPAE-based copolymer properties were thoroughly characterized. Interesting surface properties and two different values of refractive index were observed: thus, these fluorinated copolymers can be suitable materials for the manufacture of self-cleaning coatings and optical waveguides.
使用了新的全氟聚醚（PFPAE）单体，这些单体用不同的烷基进行链扩展，并以乙烯基醚或环氧端基进行官能化，同时与三羟甲基丙烷三乙烯基醚或三羟甲基丙烷三缩水甘油醚一起用于制备含氟共聚物。研究了光引发阳离子聚合反应，并对基于PFPAE的共聚物性能进行了全面表征。观察到了有趣的表面性质和两种不同的折射率值：因此，这些含氟共聚物可以是制造自清洁涂层和光波导的合适材料。
