摘      要：Functional copolymer/organo-silicate [octadecyl amine (ODA) surface modified montmorillonite (MMT)] layered nanocomposites have been synthesized by interlamellar complex-radical copolymerization of preintercalated complexes of maleic anhydride (MA)... ODA-MMT and itaconic acid (IA)... ODA-MMT as ‘nano-reactors’ with n-butyl methacrylate (BMA) as an internal plasticization comonomer in the presence of radical initiator. It was demonstrated that intercalation and exfoliation in situ processes are accompatied by physical (H-bonding) and chemical (amidization/imidization) interfacial interactions of monomers with ODA-MMT which are responsible for the formation of nanostructural hybrid architectures. The synthesized copolymers and their nanocomposites were investigated by X-ray diffraction, TGA-DSC, SEM and TEM methods. It was found that nanocomposites’ crystallinity, thermal properties and morphology strongly depended on the force of interfacial monomer... ODA-MMT complex-formation and the amount of flexible n-butyl ester linkages. An increase in both of these parameters leads to enhanced intercalation and exfoliation in situ processes of copolymer chains and the formation of hybrid nanocomposites.
