摘要
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 FT-IR 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.
