| Abstract | Thin films of titanium chloride, with and without MgCl2 have been produced, characterized, and used for in situ propylene polymerization with AlEt3. The oxidation states of Ti in the film are mainly 4+, 3+ and 2+, and their distribution varies with deposition method. Temperature programmed desorption (TPD) of mesitylene and tetramethylcyclopentadiene shows that the surface of titanium chloride film without MgCl2 has more homogeneous adsorption site distribution. Both films produce highly isotactic polypropylene. The polypropylene film grown on the titanium chloride film without MgCl2 has a rough surface, compared to that with MgCl2. |
