TiCl2(OR) complexes were synthesized and the structure of a suitable single crystal of complex 2 (R1: CH3; R2: H) was determined by X-ray diffraction. When activated by methylaluminoxane (MAO), all complexes were active for the polymerization of ethylene, styrene and MMA. The effect of variation in temperature, catalyst concentration and MAO/catalyst molar ratio was studied, and the influence of the functional group on the catalyst activity is also discussed.
