<p>This invention relates to polyolefin composites, and to a process for the in-situ preparation of a catalytically active olefin-polymerizing filler compound for polyolefin composites comprising: (a) drying a filler compound having a neutral-to acidic surface by mixing said filler compound in a liquid alkane and water and distilling an azeotropic mixture comprising said alkane and water; and (b) attaching an olefin-polymerizing transition metal compound to the dried filler compound from step (a) so as to make a catalytically active filler.</p> |
