| Abstract: | Monomer of acryloyl tri(1,1,2,2-tetrahydroperfluoro-octyl) citrate (FOC) and β-acryloyloxy 1,1,2,2-tetrahydroperfluoro-octyl propionate (FOP) were successfully synthesized and copolymerized with n-butyl acrylate by continuous process emulsion copolymerization. Thermal properties of resulting fluorinated copolymers were characterized by TGA. The water and oil repellency of the polymers used as textile finishing agent on cotton fabrics were investigated, and the surface energies were calculated. The X-ray photoelectron spectrometer (XPS) measurement showed strong surface enrichment of fluorinated segments. |
