Topological Principles of the Analysis of Binary Statistical Copolymerisation

The criteria for the estimation of the characteristics of binary statistical copolymerisation, namely composition, curves for distribution with respect to composition, chemical structure of macromolecules, and parameters of the quantitative estimate of inhomogeneity with respect to composition, are examined on the basis of the most general model of such a process. It is suggested that all copolymeric systems be divided into four classes: (1) classical; (2) classical subject to certain boundary conditions; (3) "unusual" systems of the first kind; (4) "unusual" systems of the second kind ("anomalous" systems).
The principles described are illustrated by the analysis of a number of specific models (heterophase copolymerisation, copolymerisation of ionogenic monomers in ionising media, copolymerisation of partly complexed monomers, copolymerisation complicated by reactions involving chain transfer to macromolecules or by depolymerisation reactions, etc.).
