Drago's four-parameter equation for the enthalpies of donor-acceptor association reactions was extented to the systems in which the donors were N-ethylcarbazole and poly(vinylcarbazoles) prepared under different conditions and the acceptors were various nitrofluorenones. The parameters obtained from the observed equilibrium constants were correlated to the configurations of the polymer obtained by NMR method.
