Abstract—Hydrolytic polycondensation of polydimethylsiloxane (PDMS) and polystyrene (PS) vinyldichlo-
rosilyl-terminated macromonomers yielded corresponding polymacromonomers (or molecular brushes) con-
taining latent functional groups regularly added to each monomer unit of the backbone. The optimal conditions
for preparing high-molecular-mass products were determined. The rheological study of narrow fractions of
polymacromonomers demonstrated that an increase in molecular mass shows an insignificant effect on their
intrinsic viscosity, thereby proving the assumption that these polymers occur in solution as sufficiently dense
globules. Using polydimethylsiloxane polymacromonomers, polymer-analogous transformations were per-
formed, and a highly reactive chlorosilyl derivative and a comb-shaped siloxane–hydrocarbon copolymer were
afforded.
