TL;DR: In this paper, the norbornadiene/ethylene copolymerization was studied using [Ph 2 C(Ind)(Cp)ZrCl 2 ] and [Cp 2 ZrCl2 ] catalysts in the presence of methylaluminoxane as a cocatalyst.
Abstract: The norbornadiene/ethylene copolymerization was studied using [Ph 2 C(Ind)(Cp)ZrCl 2 ] and [Cp 2 ZrCl 2 ] catalysts in the presence of methylaluminoxane as a cocatalyst. The polymerizations were carried out using a semiflow method, and the comonomer was charged batchwise into the reactor. Polymerizations were run at 60 °C at an ethylene pressure of 2.5 bar. The activities of both catalysts decreased when the norbornadiene/ethylene ratio in the reaction increased. The structural characterization of the copolymer was performed by DEPT and 1 H- 13 C 2D NMR experiments. The copolymerization of norbornadiene was shown to occur via both double bonds of norbornadiene. The polymers with high norbornadiene content were amorphous and transparent.
