The modification of PAMAM( G =3 0) dendrimers was achieved by using aldehyde, benzyl chloride and trityl chloride as reaction agents, respectively. The complexes were synthesized simply by dropping TiCl 4 solution into the modified PAMAM dendrimers that were dissolved in certain solvent. The quantity of Ti contained in the complexes increased as the adding amount of TiCl 4 was increased. The polymerization of α methyl styrene catalyzed by the complexes was accomplished and it has shown that the complexes possessed catalytic function.
