Organometallic polymers I. Solution polymerization of α‐ferrocenylmethylcarbonium fluoborate

Abstract

The self‐condensation of α‐ferrocenylmethylcarbonium ion in nitroethane yielded polymers of Mn up to 20,000. The change of [η] and Mn with the reaction time indicated that the process consisted of a rapid primary growth stage, an induction period, a second growth stage, and a crosslinking stage. The [η]–Mn correlation for a series of polymeric fractions in the Mn = 0.1–7.2 × 104 range points to a highly branched structure.
