Two novel fluorinated acrylate monomers 4a and 4b containing perfluorohexyl group were designed and synthesized starting from 4 - allylanisole and perfluorohexyl iodide. The monomers 4a and 4b were then copolymerized with octadecyl acrylate and 2 - hydroxyethyl acrylate by emulsion polymerization to give copolymers PFA 1 and PFA 2 respectively. The co-polymers were characterized by FTIR and their heat stability was measured by TGA. The surface properties of PFA 1 and PFA 2 were studied by applying on cotton fabrics. The treated cotton fabrics showed good water-repellent property, and the contact angles for water reached 142° for PFA 1 and 136° for PFA 2.
