“…In a typical experiment, the reactor was loaded with partial pressures of 20.0 mbar of CH 3 OH and 40.0 mbar of FC(O)OOC(O)F. It was necessary to add excess of peroxide, otherwise the reaction continues to the formation of CH 3 OC(O)OOC(O)OCH 3 36. Every 10 min, a small amount of the gas mixture (less than 1 % of the reactor content) was analyzed by IR spectroscopy.…”

The synthesis of CH 3 OC(O)OOC(O)F is accomplished by the thermal reaction between CH 3 OH and FC(O)OOC(O)F at room temperature. The new peroxide is obtained in pure form after repeated trap-to-trap condensation and it is characterized by NMR and IR spectroscopy and mass spectrometry. Geometrical parameters were studied by ab initio methods [B3LYP/6-31++G(d,p)]. CH 3 OC(O)OOC(O)F is stable for a few hours at room temperature, and it decomposes into CO

“…TFE was prepared by vacuum pyrolysis of PTFE 26 and stored at room temperature over d-limonene in a 300 mL stainless steel sample cylinder fitted with an 1800 psi safety rupture disk. The diethyl peroxydicarbonate initiator was prepared in Freon 113, according to a published procedure, 27 and stored at -20°C. The initiator was standardized by iodometry and was typically 7.5% (w/w).…”

Tetrafluoroethylene (TFE), chlorotrifluoroethylene (CTFE), and vinylidene fluoride (VDF) were copolymerized with vinyl acetate (VAc) in supercritical fluid CO2 by a free radical mechanism and without the use of a surfactant. A series of copolymers were synthesized with yields as high as 83% for TFE-VAc, 91% for CTFE-VAc, and 70% for VDF-VAc copolymers. Their weight-average molar masses, relative to polystyrene, were between 120 and 290 kg mol -1 , and polydispersity was between 1.6 and 2.4. A range of compositions was prepared with the amount of fluorocarbon in the copolymer varying from 13 to 84 mol %, as determined by elemental analysis. Monomer reactivity ratios were estimated using the error-in-variable method to be rCTFE ) 0.014 ( 0.05, rVAc ) 0.44 ( 0.03; rTFE ) -0.009 ( 0.06, rVAc ) 0.95 ( 0.08; and rVDF ) -0.4 ( 0.04, rVAc ) 1.67 ( 0.6. Proton NMR was used to estimate copolymer composition, based on triad sequences. These data, together with the reactivity ratio data, indicate that the fluorocarbons cross-propagate with VAc and that VAc propagates randomly. All samples were characterized by DSC for Tg with P(CTFE-co-VAc) having a Tg between 42 and 53°C, P(TFE-co-VAc) between 34 and 41°C, and P(VDF-co-VAc) between 20 and 33°C. Hydrolysis of vinyl acetate to vinyl alcohol (VA) in P(TFE-co-VAc) yielded terpolymers, P(TFE-co-VAc-co-VA), with >80% of VAc hydrolyzed to VA, thereby providing a reactive functional group for further modification. Interestingly, only a small decrease in molar mass was observed after the hydrolysis of vinyl acetate to vinyl alcohol, reflecting the loss of acetic acid and suggesting that these polymers are linear. The results presented herein are particularly interesting because no surfactant (or dispersion agent) was required for apparent solubility in CO 2. The fluoropolymers prepared herein may find utility in coatings or paint applications.

“…The initiator for the polymerisations of VDF, diethyl peroxydicarbonate (DEPDC), was synthesised according to the published methods [28]. The final product solution was approximately 10 wt% DEPDC in 1,1,2-trichlorotrifluoroethane (Freon 113), and stored at K15 8C.…”
