The nature of the substituent R strongly influenced the catalyst activity and selectivity and the copolymer microstructure and molecular weight. The catalysts derived from 1 3 were by about one order more active than those derived from 4 6. At the optimum Al/Ti molar ratio 900, the highly active catalysts produced a pseudo random copolymer (95-97 wt %) containing up to 47.8 mol % of incorporated styrene. The low-active catalysts gave mixtures of a pseudo-random copolymer (76 - 85 wt %) with polyethene (10 wt %) and polystyrene sequences (3 - 7 wt %).
