【Abstract】 Three novel fluorine-containing monomers: 2-[(trifluoroacetyloxy)]ethyl methacrylate (TFAOEMA), 2-[(trifluroacetyl)oxy]ethyl acrylate (TFAOEA), and 2-[(trifluroacetyl)oxy]propyl acrylate (TFAOPA), were successfully synthesized. Radical copolymerization of TFAOEMA, TFAOEA or TFAOPA with styrene were carried out in bulk. The monomer reactivity ratios were then determined. And the Q, e values of the three novel monomers were calculated. Moreover, the molar absorption coefficients, refractive indexes and densities of TFAOEMA, TFAOEA and TFAOPA were mjeasured.更多还原
