ABSTRACT
Poly2,2,2-砌uoroc血ylmethacrylate∽下EMA)and block copolyIners have been synthesized by liVing anionic polymedz8tion and atom仃ansfcr radical polyIllerization (ATRP) solution polyIneri删on or emulsion polyrneri刎on. The smlctⅢes of polyIners were mestigatedby服,NMR a11d DSC m01ecular
wei曲t and polydispcrs试es ofpolymers were detennined by GPc.
