The reactivity of persistent perfluoroalkyl radical, perfluoro-3-ethyl-2,4-dimethyl-3-pentyl ( 1 ), with various electron-donating reagents was investigated. It is revealed that 1 which is robust under oxidative conditions is rather vulnerable under

Liquid-phase photofluorination (LPPF) of 2-phenyl-2-methoxyhexafluoropropane 1 gave the desired F -2-cyclohexyl-2-methoxypropane, 2 , in 21% yield. An unusual rearranged product, F -2-cyclohexylmethyl isopropyl ether, 4 , and a degradation product, F

The tertiary amines derived from hexafluoropropene dimers were subjected to liquid-phase photofluorination (LPPF). The corresponding perfluorotertiary amines, which were difficult to synthesize by the conventional fluorination methods such as electro

The preparation of a new perfluoroalkylated diamine, 5-[1H,1H-2-bis(trifluoromethyl)heptafluoropentyl]-1,3-phenylenediamine, is described. Poly(amic acid)s and polyimides were prepared from this new diamine and polyimides were evaluated as films for

Theoretical calculations of miscibility windows for binary polymer blends in which one component is an essentially alternating copolymer of tetrafluoroethylene and vinyl alcohol (FVOH) are reported. FVOH has an inherently low solubility parameter [

This paper describes a novel, safe, effective technique, with a new reactor design, for the synthesis of perfluorochemicals. This method, the liquid-phase photofluorination with undiluted fluorine, is applicable to the preparative-scale synthesis of

Electron spin resonance (ESR) analysis at room temperature of the particles produced during the aerobic pyrolysis of perfluoro polymers (PFP) shows the presence of end-chain peroxyl radicals. These radicals, which would normally have lifetimes of sev

Submicrometer solid-particle (fume) aerosols with up to about 10(8) particles/cm3 are formed when dilute vapors of low molecular weight (MW) (ca. 5000-10,000) perfluoro polymers condense in air. The aerosol (e.g., 0.2 mg/m3) formed from these vapors

Spin adducts are observed when the unfiltered smoke produced during the aerobic pyrolysis of perfluoro polymers (PFP) is bubbled through a solution of the ESR spin trap alpha-phenyl-N-tert-butylnitrone (PBN). The spin adducts include those from an ox
