Synthesis and properties of novel perfluorocyclohexylated compounds with bis(perfluorocyclohexane carbonyl) peroxide

Bis(perfluorocyclohexane carbonyl) peroxide was prepared by the reaction of the corresponding acyl fluoride and hydrogen peroxide. This peroxide was a pplied to the preparation of perfluorocyclohexylated end-capped oligomers v ia a radical process under very mild conditions. In cyclic perfluorocyclohe xylated end-capped oligomers containing hydroxy segments, these oligomers c ould cause a gelation in water and in polar organic solvents such as MeOH, EtOH, dimethylformamide (DMF), and dimethylsulfoxide (DMSO), and the gellin g ability of these oligomers was superior to that of the corresponding line ar perfluorooxaalkylated oligomers. Furthermore, perfluroocyclohexylation o f polystyrene or benzene was proceeded via a single electron transfer react ion by using this peroxide. (C) 1999 John Wiley & Sons, Inc.
