Abstract
Unsaturated poly(ethylene-co-5-vinyl-2-norbornene) was synthetized using the [Ph2C(Flu)(Cp)]ZrCl2 metallocene/methylaluminoxane (MAO) catalyst system. 1H and 13C NMR spectra of the copolymer were assigned by means of DEPT, homonuclear 2D 1H-1H COSY, and heteronuclear 2D 1H-13C correlation NMR experiments. The used catalyst system produces mainly isolated 5-vinyl-2-norbornene (VNB) sequences. VNB is incorporated selectively via the cyclic double bond. The unreacted double bond of the copolymer exists in the 5-endo: 5-exo positions (3 : 1). Both isomers of VNB are polymerized with the same propability.
