The synthesis and characterisation of four polyfluorinated monoepoxides is described. These fluoroepoxy monomers were cationically polymerised either neat or as mixtures with diglycidylether of bisphenol-A using the initiator system (CH3CH2) 3Al/H2O (2/1) or the photoinitiator Ph2I+, PF6−. Contact angle measurements indicated that, in favourable cases, the fluorinated epoxide monomer surface segregated at low loadings to give significant ...
