Synthesis and surface properties of novel fluoroalkylsilyl methacrylate copolymers

The syntheses of novel mono(1H,1H,2H,2H-tridecafluorooctyl) dimethylsilylpropyl methacrylate (MFSA), bis(1H,1H,2H,2H-tridecafluorooctyl)methylsilylpropyl methacrylate (BFSA) and tris(1H,1H,2H,2H-tridecafluorooctyl)silylpropyl methacrylate (TFSA) were achieved in two steps each in good yields. These fluoroalkylsilyl methacrylate monomers (MFSA, BFSA and TFSA) readily reacted with methyl methacrylate (MMA), butyl acrylate (BA), hydroxyethyl methacrylate (HEMA) to form their corresponding fluoroalkysilyl methacrylate copolymers via continuous emulsion polymerization. The structures of fluoroalkylsilyl methacrylate monomers and copolymers were characterized by FT-IR, 1H NMR, 13C NMR and 19F NMR. The stability of copolymer emulsions was determined by measuring their particle size and zeta potential, and the thermal stability of copolymers was also evaluated by using thermo-gravimetric analysis. In addition, it was observed that improving fluorine content, increasing the packing density of fluoroalkylsilyl segments, and annealing process could enhance the excellent water and oil repellency of fluoroalkylsilyl methacrylate copolymers. The surface free energies of copolymer films were calculated. Moreover, an enrichment of fluoroalkyl chains at the copolymer surface was directly verified by measuring contact angles and using atomic force microscopy.

SYNTHESIS OF ORGANOSILICON DERIVATIVES OF ACRYLIC ACIDS

A study of the reactions of organohydrochlorosilanes with allyl acrylate showed that the addition proceeds at the β-position in all cases.The acrylate-containing chlorosilanes react with acetic anhydride to give quantitative yield of the acetoxy derivatives.Study of the hydrolysis of the chloro and acetoxy derivatives showed the feasibility of the direct synthesis of the corresponding silanols.The reactivity of these compounds was studied.
