✦ Synopsis

Inverse gas chromatography at mfimte dllutlon has been used to study the effects of modifications of catlomc (montmonllonlte) and anionic (hydrotalclte) clays By using alkanes and alkenes as probe molecules both the chsperslve component of the surface energy and the surface aadlc sites were characterized The mtroductlon of polymers mto the structure of these minerals slgmficantly changed then chemical character Carbonization of samples whose mterlayer spaces were saturated with polymers produced new carbon-modified matenals These composite materials became mlcroporous whde retammg then initial acid/ base surface properties
