Polymerisation and related reactions involving nucleophilic aromatic substitution. Part 3. Mathematical models of the polycondensation reactions of halogenobenzophenones

Abstract

Linear free energy relations have been used to calculate rate coefficients for the stages in the polycondensation reaction of the potassium salt of 4-fluoro-4′-hydroxybenzophenone and for the polycondensation reactions of 4,4′-difluorobenzophenone with the dipotassium salt of 4,4′-dihydroxybenzophenone and the dipotassium salt of hydroquinone. These rate coefficients have been used in a kinetic model of the polycondensations to calculate how the concentrations of the individual molecular species formed vary with time. The kinetic model is used to show that the molecular composition of the solutions, when considered as a function of the percentage reaction, should be relatively insensitive to the initial monomer concentration and to medium effects provided that all of the species concerned are fully soluble.
