Abstract
A stereoregular and Bernoullian copolymer of styrene and ethylene was produced by the catalyst system of rac-[isopropylidenebis(1-indenyl)]z irconium dichloride and MAO. This catalyst system yields a high molecu lar weight copolymer with good activity at 50 degrees C. The copolymer consists of Et-Et, St-Et, and head to tail St-St sequences and has a highly isotactic Et-St alternating sequence. This copolymer shows a me lting point (80-110 degrees C), due to the isotactic alternating seque nce.
