✦ Synopsis

N-oxide oligomers were obtained as the reaction products as illustrated in the scheme New perfluoropropylated and perfluoro-oxaalkylated 4-vinylpyridinium chloride oligomers with carbon -carbon bond formation were prepared by the reactions of the corresponding fluoroalkanoyl peroxides with 4-vinylpyridinium chloride in excellent to moderate yields under very mild conditions. These fluorinated oligomers were effective for reducing the surface tension of water to around 10 mN m 01 with a break point resembling a CMC ( critical micelle concentration ) , and are applicable to new fluorinated cationic oligosurfactants.

New fluoroalkyl end-capped oligomers containing pendant phosphoric acid groups were prepared by the reactions of the corresponding monomer with fluoroalkanoyl peroxides. It was demonstrated that not only strong aggregations of fluoroalkyl segments but also hydrogen bonding could interact synergistic
