F) ABSTRACT: Fluoropolymers are valuable materials endowed with outstanding properties that allow them to be involved in many High-Tech applications [1]. This presentation aims at reporting how the design of functional fluoropolymers may influence the properties and applications. Actually, 2-trifluoromethacrylic acid (MAF) is a versatile building block for the synthesis of new functional monomers. [2] It can be homopolymerized by anionic initiation [2-3] but fails in the presence of any radical systems. However, its radical copolymerization with vinylidene fluoride (VDF) has been successful. This presentation reports overall strategies to synthesize novel functional 2-trifluoromethacrylate monomers and macromonomers, as well as their radical copolymerization with VDF, leading to various materials such as higher thermal stable thermoplastics,[4] polymer gel electrolytes for Lithium ion batteries,[5-7] and anticorrosion [8] and adhesive hybrid coatings [9] (Figure 1). Figure 1 shows the overall strategies to synthesize novel functional 2-trifluoromethyl monomers from 2-trifluoromethacrylic acid (MAF) and their radical copolymerization with VDF (left). The figure also shows steel plates coated with poly(VDF-co-MAF Phosphonate) copolymer at the beginning of the experiment (A), after 1 h (B), and after 18 h (C). (D): uncoated steel plate used as reference sample after 1 h (right). Tosoh FineChem Corporation (Shunan, Japan) is acknowledged for suppling MAF monomers. References: [1] B. Ameduri, and H.
