✦ Synopsis
Poly(ally1benzene)s were synthetised by Ziegler-Natta catalysts: [VCl, + Al [CH,CH(CH, ) , 1, ] and [TiC14 + Al [CH2CH(CH,)2I3]. Two different polymers were obtained. Examination of their microstructures by IR and 'H 13C NMR spectroscopy suggests that one of the polymerization mechanisms proceeds via isomerization of allylbenzene.
