Abstract

Abstract: With the presence of the synthesized amphiphilic reversible addition-fragmentation chain transfer (RAFT) agent, poly(2,2,3,4,4,4-Hexafluorobutyl acrylate-co-styrene) latexes were prepared via emulsifier-free emulsion polymerization. The effects of the amphiphilic RAFT agent and polymerization temperature on the polymerization kinetics, controllability of polymerization and latex particle sizes were studied. The chemical structure, Tg, molecular weight，molecular weight distribution of copolymer and surface property of the latex films were characterized by FTIR, 1H NMR, DSC, GPC and surface tension instrument, respectively.

Key words: amphiphilic RAFT agent, emulsifier-free emulsion polymerization, fluorinated copolymeracrylate
