Abstract: 
polyethylene-nanocomposites with caCO3-weight fractions from 0 to 15 wt.% were prepared by in-situ polymerization with Me2Si(Ind)2ZrCl2/MAO metallocene catalysts. A high activity especially in the presence of TIBA was observed. The morphology was investigated by using raster electron microscopy (REM) showing that the caCO3-nanoparticles are uniformly distributed. The melting temperatures and the crystallization temperatures are not much influenced by increasing filler content.
