Detailed investigation of infinite dilution sorption of organic vapors (C-7-C-16 n-alkanes, toluene, octafluorotoluene, p-fluorotoluene, 2,3,4,5,6-pentafluorotoluene, perfluorooctane) in perfluorinated copolymer AF1600 (random copolymer of 35 mol % perfluoroethylene and 65 mol % 2,2-bis-(trifluoromethyl)-4,5-difluoro-1,3-dioxole) was performed by inverse gas chromatography (IGC). C-13-C-16 n-alkanes were studied in the temperature range including both glassy and rubbery states of the polymer, while sorption of other solutes was investigated only in the glassy state of the perfluorinated copolymer. Retention diagrams of C-13-C-16 n-alkanes showed breakpoints at similar to 150 degrees C which corresponds to T-g of A F1600. Thermodynamic analysis of IGC data in rubbery and glassy states was performed based on the model developed earlier which included evaluation of Flory-Huggins interaction parameter chi and glassy state structual parameters: excess free volume phi(0)(v) polymer cohesion energy epsilon(22), and entropy depression term s(12). It was shown that aliphatic and aromatic hydrocarbons were poor solvents for glassy A F1600. Positive chi values substantially increased when the length of the alkane increases. Fluorinated hydrocarbons were, however, good solvents for AF1600, and their quality improved with the increase in fluorination degree. On the basis of the cohesion energy of AF1600 (-17.76 kJ/mol) evaluated by CAChe 7.5 molecular modeling package, excess free volume of AF1600 in the glassy state was found to be close to 0.12 and slightly dependent on temperature. The entropy effect of sorption in glassy polymer was highly negative with entropy depression proportional to molar volume of solute.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 29390-67-8 is helpful to your research. COA of Formula: https://www.ambeed.com/products/29390-67-8.html.

Organic-organic pervaporation was studied for high free volume material-amorphous Teflon AF2400 (copolymer of 2,2-bis-trifluoromethyle-4,5-difluoro dioxole and tetrafluoroethylene). Individual organic components-acetone (A), chloroform (Ch) and methanol (M) that are capable of forming azeotrope mixtures as well as binary mixtures A-Ch and M-Ch were tested as penetrants. The process was studied at different temperatures (10-50 degrees C) over a wide range of composition of mixtures (10-90%). Evidence of formation of associates between the components in the mixtures in the liquid phase and during mass transfer through the films were obtained. IR spectra and quantum-chemical calculations supported these conclusions. (c) 2005 Elsevier B.V. All rights reserved.

The photocatalytic activity promoted by anodized titanium surfaces coated with different amorphous perfluoropolymers was evaluated. A copolymer between tetrafluoroethylene and perfluoro-4-trifluoromethoxy-1,3-dioxole and two perfluoropolyethers containing ammonium phosphate and triethoxysilane functionalities, respectively, were tested as coating materials. These coatings revealed good adhesion to the anodized titanium substrate and conferred to it both hydrophobicity and oleophobicity. The photocatalytic activity of the coating on anodized titanium was evaluated by monitoring the degradation of stearic acid via Infrared spectroscopy. The degradation rate of stearic acid was reduced but not set to zero by the presence of the fluorinated coatings, leading to the development of advanced functional coatings. The morphological variations of the coatings as a result of photocatalysis were also determined by atomic force microscopy. (C) 2013 Elsevier B. V. All rights reserved.

Permeability (P) and diffusion (D) coefficients of perfluoro-2,2-dimethyl-1,3-dioxole-tetrafluoroethylene copolymers were determined with respect to different gases (He, H-2, O-2, N-2, CO2, hydrocarbons C-1-C-3). The copolymers with large content of perfluorodioxole comonomer exhibit high permeability with respect to lighter gases comparable to that of poly(trimethylsilyl propyne). However, the copolymers studied are much more permselective than the latter polymer. Free volume as estimated via Bondi’s method and free volume size distribution parameters which were determined by means of positron annihilation lifetimes (PAL) method are also unusually high if compared with other glassy polymers. A novel correlation of the P and D values, as well as of the solubility coefficients S with the PAL parameter tau(4)I(4) are reported.

Amorphous fluorinated optical polymers, characterized by high transparency in the visible and near infrared spectra, high glass transition temperature and very good resistance to chemical environment, have been developed by co-polymerisation of tetrafluoroethylene (TFE) and 2,2,4-trifluoro-5-trifluoromethoxy-1,3-dioxole (TTD). In this work we study at molecular level the effect of the introduction of the bulky TTD unit in a perfluoroalkyl chain. In particular the effect on the molecular structure and chain flexibility is investigated and spectroscopic markers correlated to chemical and structural defects are identified. The study includes a thorough experimental spectroscopic analysis (infrared and Raman spectra) of several different copolymer samples and a modelling based on Density Functional Theory calculations and semiempirical calculations on suitable model molecules.
