Telomerization Reaction of 3,3,3-Trifluoropropene

Various strategies for syntheses from original telomers toward controlled fluoropolymers based on 3,3,3-trifluoropropene (TFP) are depicted in this review. Telomerization involves a telogen or a transfer agent (X–Y), and one or more (n) molecules of a polymerizable compound M (called taxogen or monomer), under radical polymerization conditions, leading to X–(M)n–Y telomers, as follows: Figure options Download full-size image Download as PowerPoint slide More specifically, (co)telomerizations of TFP involving different X–Y chain transfer agents (CTAs, phosphonated or halogenated) are summarized. The kinetics of telomerization enabled the assessment of the transfer constants to the CTAs, whereas cotelomerization has also been of great interest. This chapter also focuses on the applications of these functional (co)telomers as potential intermediates for the synthesis of well-architectured fluoropolymers including telechelics, macromonomers, and block copolymers. Various examples are supplied to illustrate the wide potential of applications of these fluoropolymers and potential nonbioaccumulable surfactants. Another feature deals with the controlled radical polymerization of TFP in the presence of various CTAs (1-iodofluoroalkanes or xanthates) for original surfactants, the properties of which are discussed. Applications will be the main highlight of this chapter.
