“…E‐4 and E‐3 coated cotton fabrics had much lower WAC than E‐2 and E‐1 coated cotton fabrics, which was consistent with the results of CA. These observations further demonstrated the results that the polymers including organosilicon, organofluorine, or organofluorosilicon indeed exhibited an excellent water‐repellency, which was reported in the literatures . The extent of the decease of WAC depended on hydrophobicity of the coated cotton fabrics, that is to say, the more hydrophobicity, the lower WAC.…”

This paper described the synthesis of copolymer emulsions of fluorine and siloxane-containing acrylates for waterrepellent cotton fabrics coatings. Chemical composition, morphology structure, and properties of the latex copolymers were investigated by Fourier transform infrared (FTIR), dynamic light scattering (DLS), gel permeation chromatography (GPC), and transmission electron microscopy (TEM), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). Effects of water-repellent functional monomers (R f ) on surface morphology, water contact angle, and water-repellent properties of the coated fabric surface were also studied. The results indicated that R f greatly influenced molecular mass distribution of the latex copolymers, the molecular aggregation states and orientation of R f on the coated fabric surface, and water-repellency of coated cotton fabrics.

Based on the unsaturated derivatives of polyfluoroalkanols chemical products are used to protect solid and fibrous materials surface from the effects of water, oils and other pollutants. A method for obtaining allyl ethers of polyfluoroalkanols (polyfluoroalkoxypropenes) is based on the Williamson ether reaction. This method is a heterophase process. The use of solvents to improve mass transfer requires complementary measures to ensure industrial and environmental safety. It is more preferable to obtain the target ethers in water with PTC. A series of experiments using different chain length polyfluoroalkanols was studied by GLC. Kovats retention indexes of the target ethers were determined. It was found that in the case of lower homologues (CF3CH2OH, (CF3)2CHOH, HCF2CF2CH2OH), the addition of 5-15 vol.% 1,4-dioxane as a solubilizer provides a high yield of products. The application of PTC (tetrabutylammonium bromide) is indispensable for using polyfluoroalkanols with a longer carbon chain (C≥5). PTC invariably provides the almost complete conversion of polyfluoroalkanols. The decomposition process of TBAB becomes noticeable (GLC method) upon completion of the main reaction. Polyfluoroalkoxypropenes form azeotrope with water, which can be used in the work up process.
