Abstract
Ethene-1,3-butadiene copolymerizations in the presence of CpTiCl3/MAO catalytic system were performed. The microstructure of the obtained copolymers and the activity were reported as a function of the Al/Ti ratio. At high Al/Ti ratio prevailingly 1,4-cis butadiene homosequences were obtained, whereas, at low Al/Ti ratio, over 50% of alternating ethene-1,4-trans-butadiene was produced. The activity shows a minimum value at Al/Ti = 128.
