Synthesis of a novel perfluorooctylated polyacrylate and its application on cotton fabrics

Abstract A perfluorooctylated acrylate monomer (FAC) containing a urethane linkage was synthesized, and fluorinated polymers [perfluorooctylated polyacrylate (PFAC)] were obtained from the copolymerization of FAC with other acrylate monomers by emulsion polymerization. The size of the emulsion particles was about 40–60 nm. PFAC was applied to cotton fabrics by a pad–dry–cure process. The treated fabrics that were dried at 100°C after being washed showed good water and oil repellency: the water repellency rating and the oil repellency rating were 100 and 5, respectively. Those dried at room temperature also showed water and oil repellency: the water repellency rating was 70 and the oil repellency rating was 3. © 2005 Wiley Periodicals, Inc.
