Silicoaluminates as “support activator” systems in olefin polymerization processes [PDF]
, 2010 In this work we report the polymerization behaviour of natural clays (montmorillonites, MMT) as activating supports. These materials have been modified by treatment with different aluminium compounds in order to obtain enriched aluminium clays and to ...
