Abstract
We consider the complex polymer system, consisting of a ring polymer connected to the -branched starlike structure, in a good solvent in the presence of structural inhomogeneities. In particular cases and , such a system restores the synthesized tadpole-shaped polystyrenes [Doi et al., Macromolecules 46, 1075 (2013)]. We assume that structural defects are correlated at large distances according to a power law . Applying the direct polymer renormalization approach, we evaluate the universal size characteristics such as the ratio of the radii of gyration of star-ring and star topologies, and compare the effective sizes of single arms in complex structures and isolated polymers of the same total molecular weight. The nontrivial impact of disorder on these quantities is analyzed.
