Polyamide 6/silica hybrid materials are fabricated by the activated anionic polymerization ofε-caprolactam (ε-CL) with lactam-substituted silane monomers Si(ε-CL)4, Me2Si(ε-CL)2and Me3Si(ε-CL), respectively. All three silane monomers are excellent activators for the anionicε-caprolactam polymerization initiated by EtMgBr, resulting in short reaction times of a view minutes and high polymer yields. Studies on the thermal decomposition behavior of the lactam containing silanes indicate the formation ofN-iminolactams, which influence the activation process as well as the pathway of the inorganic filler formation. The molecular structure and morphology of the hybrid materials have been investigated by solution and solid-state NMR and FTIR spectroscopies as well as electron microscopy and size exclusion chromatography measurements. As consequence, lactam-substituted silane monomers serve both as activator and reactant in the synthesis of PA/silica and related hybrid materials.
