The main theoretical problems encountered in the microstructural analysis of (pseudo)copolymers have been discussed. The theoretical framework for the application of Markovian models in this field has been established by arguments of information theory. As indicators of microstructural regularity, which are independent from models of polymerization kinetics, block lengths and redundancy estimates have been presented and discussed. Redundancy estimates are tightly connected to the informational entropy and can be obtained with minor effort from experimental data. Literature microstructural data of ethylene‐propylene copolymers and polypropylenes have been examined in order to give practical examples of the computation of the indicators, which are found to easily describe the main features of the samples examined.
