【Abstract】 Poly（styrene-butadiene-styrene）（SBS） were modified by reacting with （R_fCO₂）₂ in CH₂Cl₂ at room temperature to give R_f-SBS polymers. All the fluoroalkylated products were characterized by IR and ¹9F NMR spectra. It is shown that R_f and R_fCO₂ groups were only added onto the double bonds of SBS polymer chain via single electron transfer（SET） mechanism. The R_f-SBS polymers showed good water- and oil- repellency and low refractive indices.更多还原
