| Abstract | Step-growth radical copolymerization between α,ω-diiodoperfluoroalkanes (A) and α,ω-unconjugated dienes (B) proceeds efficiently through a photo-induced Step Transfer-Addition & Radical-Termination (START) strategy in aqueous/organic biphasic system. The addition of water in our polymerization strategy enhanced the overall polymerization efficiency and inhibited the function loss (C–I) significantly, which has been illustrated through UV-vis tests. Therefore, most of the functional groups (C–I) in the polymer chain end have been preserved in the final polymer product (AB)n based on 19F NMR analysis. After polymerization, we could erase the iodine atoms in the main chain of (AB)n, which generates semifluorinated polyolefins with enhanced thermal stability. |
