Synthesis,characterization and polymerization of the novel carbazole‐based monomer 9‐(bicyclo[2.2.1]hept‐5‐en‐2‐ylmethyl)‐9H‐carbazole

Synthesis and characterization of a novel carbazole‐based monomer, 9‐(bicyclo2.2.1]hept‐5‐en‐2‐ylmethyl)‐9H‐carbazole (BHMCZ) and its copolymerization with ethylene by using two metallocene/MAO catalyst systems are presented. The monomer was characterized by means of NMR spectroscopy, MS and elementary analysis. Copolymerization studies were conducted using Ph₂C(Ind)(Cp)ZrCl₂] and Ph₂C(Flu)(Cp)ZrCl₂] catalysts. The Ph₂C(Ind)(Cp)ZrCl₂] catalyst gave a copolymer containing as much as 4.6 mol‐% of BHMCZ. Polymers were characterized using NMR spectroscopy, gel permeation chromatography (GPC) and differential scanning calorimetry (DSC).
