　　Carbon nanospheres(CSs) treated with Grignard reagent was used as carrier,which reacted with TiCl4 to form supported Ziegler-Natta catalyst.In the presence of AlEt3,this catalyst catalyzed ethylene polymerization to obtain PE/CSs composite in situ.The catalytic activity for ethylene polymerization was up to 5.7×106 gPE/moiTi.h and the weight average molecular weight of the obtained polymer was 4.9×l05g/mol.
