UNLABELLED
Several difunctional oligomers were synthesized by functionalizing perfluoropolyalkylether (PFPAE) chains with different vinyl ethers and epoxides end-groups. Due to their innate synthetic challenges and demanding purification protocols, the PFPAE derivatives were obtained in low yield and with an average functionality lower than 2. However, the functionalized PFPAE oligomers were successful in being used in photo-induced cationic polymerization processes, obtaining transparent and soft films. The influences of the fluorinated chains, and various end-groups on the photopolymerization process were investigated, as well their chemical stability, thermal degradation, and surface properties.

未标注
通过用不同的乙烯基醚和环氧端基对全氟聚醚（PFPAE）链进行官能化，合成了几种双官能低聚物。由于其固有的合成挑战和苛刻的纯化方案，PFPAE衍生物的产率较低，平均官能度低于2。然而，官能化的PFPAE低聚物成功地用于光引发阳离子聚合过程，得到了透明且柔软的薄膜。研究了氟化链和各种端基对光聚合过程的影响，以及它们的化学稳定性、热降解和表面性质。
