Saturated model compounds, related to elastomers that are derived from copolymers of CH 2 =CF 2 /CF 2 =CFCF 3 , have been synthesised and studied. Unsaturated compounds were obtained by both base‐ and Lewis‐acid induced processes. Some reactions with antimony pentafluoride lead to remarkably stable carbocations, and even di‐cations, and the nmr data for these systems is revealing about structure. Polyconjugated polymers may be obtained by this procedure. Preliminary studies are described, relating to the incorporation of crowded monomers into fluorocarbon polymers, ultimately, as a means of initiating cross‐linking processes for curing elastomers.
