Abstract
• Olefin-diene copolymns. in the presence of C2 sym. zirconocene rac-[CH2(3-tert-butyl-1-indenyl)2]ZrCl2/MAO catalytic system have been reported and rationalized by exptl. and mol. modeling studies. Ethene gives 1,2-cyclopropane and 1,2-cyclopentane, 1,3-cyclobutane, and 1,3-cyclopentane units in copolymn. with 1,3-butadiene, 1,4-pentadiene, and 1,5-hexadiene, resp. Propene-1,3-butadiene copolymns. lead to 1,2 and 1,4 butadiene units and to a low amt. of 1,2-cyclopropane units.File in questo prodotto:
