Abstract
Disclosed is clay material, the particles of which are intercalated with a compound comprising a saturated isoprene oligomer bonded to a polar group. In a preferred embodiment the polar group is a quaternary ammonium radical. Further disclosed is a nanocomposite comprising C.sub.2 -C.sub.3 .alpha.-olefin polymer material, and, dispersed in the matrix of the olefin polymer material, exfoliated clay material, the particles of which before exfoliation were intercalated with said compound.
