Anionic polymerization of multi-Vinylferrocene (cas 1271-51-8)s

Protocols for anionic polymerization of vinylferrocenes in bulk (b) and solution (s) are reported. Polymerization of vinylferrocenes bearing one or multiple (2–4) vinyl groups yielded linear polyvinylferrocene PVF-1(b, s) or cross-linked polyvinylferrocenes PVF-2 – PVF-4(b, s), respectively. Furthermore, copolymerization of mono-with multifunctional vinylferrocenes produced cross-linked copolymers PVF-5 – PVF-7(b, s). For anionic polymerization in bulk, a high monomer conversion and a relatively high dispersity was observed. A reversible redox behavior of the ferrocenyl group with cycle stability up to 100 cycles was found for PVF-(1s – 7s). Li-ion battery cell tests demonstrated the applicability of the polyvinylferrocenes PVF-1b and PVF-(5b – 7b) as electrode materials.
