The copolymerisation of 2,4-dicyanobut-1-ene with N-vinyl carbazole

The copolymerisation of the monomers 2,4-dicyanobut-1-ene and N-vinyl carbazole has been studied. The presence of a charge transfer complex from these two monomers with a 1:1 stoichiometry has been established, and a value of 0.22 dm 3 mol −1 at 298 K for the equilibrium constant for complex formati...

Description
Summary:The copolymerisation of the monomers 2,4-dicyanobut-1-ene and N-vinyl carbazole has been studied. The presence of a charge transfer complex from these two monomers with a 1:1 stoichiometry has been established, and a value of 0.22 dm 3 mol −1 at 298 K for the equilibrium constant for complex formation has been obtained from NMR measurements. The copolymer composition data have been analyzed allowing for the participation of the complex in the propagation reactions; the results have been compared with the predictions of two simpler terminal models and with the penultimate model.
