Synthesis and hydrodynamic and conformation properties of star-shaped polystyrene with calix[8]arene core

Abstract

Properties of individual molecules of star-like polystyrene with calix[8]arene core in dilute chloroform solutions were studied using methods of static light scattering, translation diffusion, and viscometry. The solution behavior of the polymer investigated significantly differs from the properties of linear polymers. Star-like polystyrene macromolecules in solutions are characterized by compact structure—the hydrodynamic radius is not higher than 5.5 nm at M = 125,000 g⋅mol−1. The shape of star-like polystyrene macromolecules differs slightly from spherical.
