Abstract
• 2-Phenyl-1,3-butadiene and (E)-1-phenyl-1,3-butadiene were polymd. in the presence of homogeneous Ziegler-Natta catalytic systems. The products were analyzed by means of 13C NMR spectroscopy. Monomer reactivities and polymer structures were compared with those obtained by using the same catalytic systems in the polymns. of isoprene, (E)-1,3-pentadiene and 1,3-butadiene. The results were tentatively rationalized by considering the stability of the allyl groups resulting after any insertion of the monomer into the growing chain.File in questo prodotto:
