Use of Radiation-Synthesized Tetrafluoroethylene Telomers with Silane End Groups for Hydrophobization of Polyester Fabric
High Energy Chemistry, 2020Co-Authors: G. A. Kichigina, N. P. Prorokova, P. P. Kushch, Dmitrii P. Kiryukhin, T. Yu. KumeevaAbstract:The optimal parameters of radiation-initiated synthesis in trimethylchlorosilane of Tetrafluoroethylene telomers intended for hydrophobization of polyester fabrics have been determined. The efficiency of using Tetrafluoroethylene telomers with silane end groups as water repellents has been evaluated. It has been shown that treatment of polyester fabric with Tetrafluoroethylene telomer solutions makes it possible to form a highly hydrophobic coating characterized by a contact angle of water of about 120° and high resistance to factors affecting the performance. The hydrophobized fabric possesses uniquely low water absorption and good hygienic properties.

Kinetics and mechanism of radiation telomerization of Tetrafluoroethylene in hexafluoropropan-2-ol and trifluoroethanol
Russian Chemical Bulletin, 2017Co-Authors: G. A. Kichigina, P. P. Kushch, D. P. Kiryukhin, Svetlana I. Kuzina, Alfa I. MikhailovAbstract:The kinetics of radiation telomerization of Tetrafluoroethylene (TFE) in trifluoroethanol and hexafluoropropan-2-ol (HFIP) has been investigated by method of kinetic calorimetry. The nature of active centers initiating the process of telomerization of Tetrafluoroethylene in hexafluoroisopropanol in the temperature range of 77—300 K was investigated by ESR spectroscopy. The molecular structure and properties of the obtained telomeres were studied by IR spectroscopy and TGA.

Radiation-induced cotelomerization of Tetrafluoroethylene with methylacrylate and Tetrafluoroethylene with acrylamide in methylene chloride solutions
Russian Journal of Applied Chemistry, 2015Co-Authors: A. I. Bol’shakov, S. I. Kuzina, D. P. KiryukhinAbstract:Kinetics of radiation-induced cotelomerization of Tetrafluoroethylene with methyl acrylate and terafluoroethylene with acrylamide in solutions of methylene chloride was studied. The synthesis process occurs under the conditions of kinetic chain transfer to the telogen, which involves only the radical with a terminal fragment of Tetrafluoroethylene, whereas methyl acrylate or acrylamide molecules are added to the growing telomer chain. The composition of the telomer and its properties depend on the relative reactivities of the monomers in the chain-growth reaction. The incorporation of methyl acrylate into the telomer chain results in that the molecular mass and the fraction of the soluble fraction of the cotelomer become larger. It was found that the adhesion properties of fluorine-containing coatings formed on the basis of cotelomers of Tetrafluoroethylene and methyl acrylate are improved.
