The dependence of the compatibility of a modified montmorillonite 
with different-polarity polymers on the structure of a modifier layer 
formed on the montmorillonite surface has been investigated. It is 
shown that the layers forming an ordered structure in the interplane 
spaces of the clay do not provide an exfoliation of the silicate plates 
of the clay or a significant intercalation of polymer chains into 
the interlayer space of the montmorillonite. An optimum structure 
of a modifier layer, providing a significant intercalation of polymer 
chains into the interlayer spaces of the montmorillonite and an exfoliation 
of the clay in its compounds with a maleinized polypropylene, obtained 
by mixing in a melt, has been determined.
