A novel TiCl 4 /MCM-41 catalyst was prepared for ethylene polymerization. MCM-41 had one-dimension and hexagonal porous structure. With this catalytic system, the nano-polyethylene fibres could be synthesized when the active sites on the exterior of MCM-41 were destroyed by hydroxy groups in β-cyclodextrin. The diameter of the resulting fibre is about 50nm, which suggests that TiCl 4 ...
