摘要

Fluoropolymers are commonly used in high-end applications, such as aerospace and microelectronics. They exhibit a unique combination of properties, including thermal stability, chemical inertness, self-extinguishing, and peculiar surface and electric properties. However, fluoropolymers also have some drawbacks, including poor adhesion to substrates and inertness to chemical modification, which limit their interactive and reactive properties. Unfortunately, the function-alization of fluoropolymers has been a constant research challenge in the past. Most research approaches have been focusing on the copolymerization of fluorinated monomers with functional comonomers to form functional fluoro-copolymers containing pendent functional groups. Few reports discussed the preparation of telechelic fluoropolymers containing terminal functional groups. The chemistry involves the use of functional initiators, including diester peroxides and diiodo initiators. Recently, Saint-Loup et al. prepared telechelic VDF/HFP elastomers containing two opposing hydroxy terminal groups by using hydrogen peroxide as an initiator. However, many side reactions occurred in this polymerization, and the final product contained not only hydroxy terminal groups but also carboxylic acid terminal groups as well as some unsaturated terminal groups.
