英文摘要: In the present paper, phenylethylene-butyl acrylate-vinyl triethoxy siloxane terpolymer, as SPME coating, was synthesized. Combining infrared spectrum and ultraviolet spectrum, the contents of the monomers were determined. The two monomers' mole ratio of phenylethylene to butyl acrylate was obtained by IR The content of phenylethylene was obtained by UV. Then the contents of butyl acrylate and vinyl triethoxy siloxane were calculated from the phenylethylene quantity and the mole ratio. For the determination of the mole ratio of phenylethylene to butyl acrylate, the standard curve was A(r) =0.114m, +0. 032 (A: absorptance ratio, mn,: mole ratio), and the correlation efficient(r(2)) was 0. 999 3; for the determination of the content of phenylethylene, the standard curve was Delta A=0.078 6c+0.081 2(Delta A: absorptance difference, c: concentration of phenylethylene), and the correlation efficient(r(2)) was 0. 998 9. The relative standard deviation (RSD) for phenylethylene was 0. 41%, and recoveries were 97. 8%-104%. The relative standard deviation (RSD) for butyl acrylate was 0. 39%, and the recoveries were 97. 1%-99. 6%.
