Abstract
The authors propose an approach to the description of the configurational statistics of branched polymers allowing for the unit heterogeneity of the macromolecules arising from the fact that monomer units of one type differ in the number of groups reacting in them. With this approach the configurational statistics is characterized by the fractions of arbitrary sampling sequences with different values of the number of monomer units in them. Each such sequence represents a fragment of the molecule consisting of k monomer units joined together, taking into account the topology of the bonds joining them. The relations between the fractions of sequences 3ith different values of k which may be used for treating the results of NMR spectroscopy are presented. The algorithm of calculating the probabilities of the arbitrary sequences by the methods of the theory of random branching processes is formulated.
