Fluoropolymers synthesis

This chapter is divided into three main sections fluoropolymer synthesis, nonfluorinated polymer synthesis, and polymer characterization in C02. In the fluoropolymer synthesis section, solution, precipitation, biphasic, and continuous polymerizations will be described. Several examples of nonfluorinated heterogeneous chain-growth polymer syntheses will be followed by step-growth polymerizations. A brief summary of polymer characterization methods in C02 will conclude the chapter.

The application of SCCO2 to the synthesis and modification of well-defined polymers has enormous potential and as such has been extensively investigated. " One of the earliest reactions studied was fluoropolymer synthesis. 

Industrially, SCCO2 has been used extensively in polymer processing and synthesis. During the last 10 years, DuPont built a plant that can produce 1000 tonnes of Teflon and other fluoropolymers per year. The polymers produced in this plant are claimed to have superior performance and processing capabilities. Carbon dioxide is seen as the most viable industrial solvent for fluoropolymer synthesis, as hydrocarbon solvents can cause detrimental side... 

SCCO2 is largely used to process food (extraction or fractionation), but other applications, such as the fluoropolymer synthesis by DuPont, hydrogenation or alkylation by Thomas Swan, coatings by Union Carbide, and polyurethane processing by Crain Industries, are still in development [111]. The application of supercritical fluids (SCFs) as reaction media with homogeneous catalysts has been mainly investigated on a laboratory scale.
