Brushshaped molecular stars of poly(εcaprolactone)blockpoly(oligo(ethylene glycol) meth
acrylate) are synthesized, their hydrodynamic properties are studied, and their molecular characteristics are
measured. For dilute solutions of the copolymers in acetone, viscous flow, velocity sedimentation, and trans
lational diffusion of the macromolecules are investigated. The molecular masses of the copolymers are deter
mined via the Svedberg relation. Correlations between hydrodynamic characteristics and molecular masses
in the range 46 <M × 10–3 g mol–1 <266 are obtained. The existence of scaling relationships makes it possible
to infer that the resulting copolymers belong to a hydrodynamically similar series of macromolecules: hydro
dynamic homologs. It is shown that copolymer macromolecules have a denser organization in space than that
of both linear macromolecules and conventional molecular stars. A model of macromolecules of poly(ε
