摘要：

The cationic Ziegler-Natta polymerisation catalyst [Zr(eta-C(5)H(5)Me(thf)](+), is intercalated in a synthetic fluorinated mica-type silicate (NaMg2.5Si4O10F2) and the modified, swelling synthetic hectorite [LaponiteRD, Na0.46Mg5.42Li0.46Si8(OH)(4)O-20], by ion-exchange of [Zr(eta-C(5)H(5)Me(thf)](+) ions with the interlamellar cations of the layered silicates; in the presence of methylalumoxane {MAO, (MeAlO)(n)} these organometallic intercalation compounds are active catalysts for the polymerisation of propene giving low molecular mass atactic polypropylene with a narrow molecular mass distribution.
