Abstract
The structural changes in the potassium graphitide KC24 in its interaction with ϵ‐caprolactone, γ‐butyrolactone and pivalolactone are examined by profilometric measurement and electron scanning microscopy. The interaction of KC24 with a nonpolymerizable lactone‐γ‐butyrolactone proceeds without delamination of the graphitide. The polymerization of ϵ‐caprolactone and pivalactone in the interlayer spaces of KC24 leads to destruction of the initiators structure. An increase in the temperature and monomer concentration enhances the delamination of the graphitide.
