Notes:
This article is the first of a series devoted to various aspects of exchange reactions in molten bisphenol-A polycarbonate-poly(butylene terephthalate) mixtures. The statistical aspects of exchange reactions between two polycondensates of different chemical structure are considered. This theoretical approach enables us to calculate the mean lengths of the various sequences as well as several expressions for the degree of randomness in four-component copolycondensates from triad or dyad concentrations as determined by NMR spectroscopy.
