Description	Přírodní vermikulit posloužil jako hostitel pro QUAT intekalace a následnou polymerizaci in-situ PVAc. Průměrná velikost krystalitů polymerního nanokompozitu je dvojnásobná ve srovnání s jeho organofilním prekurzorem. (cs) Natural vermiculite served as a host for intercalation with quaternary ammonium salt (QUAT) followed by in-situ polymerization of polyvinyl acetate (PVAc). We studied the structural changes of organovermiculite and its PVAc nanocomposite with the help of X-ray diffraction analysis. The mean crystallite size of PVAc nanocomposite is double compared to that of organo-vermiculite and its distribution of crystallite sizes presents a broader region but more uniform values than the curve calculated for organovermiculite. Molecular dynamic calculation proved a monolayer arrangement of QUAT guests and a bilayer- like system of guest organic molecules in the vermiculite gallery.
