Summary: Soluble carbon nanotubes were prepared by treating SWNTs with sec ‐butyllithium and subsequently using the generated carbanions as the initiator to graft P t BA and P t BA‐ b ‐PMMA onto the surface of SWNTs. The anionic polymerization initiated by SWNTs‐bearing carbanions not only provides a powerful strategy for functionalizing SWNTs but also gives us knowledge of the sidewall chemistry of SWNTs. The results indicate that a carbanion born on SWNTs behaves like an anionic initiator with high steric hindrance.Anionic polymerization of (meth)acrylate monomer.
