Poly-N-vinylpyrrolidone-based amphiphilic polymers, which can be used as drug carriers, were prepared by radical polymerization with a thiol-type chain transfer agent. The polymers did not contain sequences of hydrophilic and hydrophobic fragments in the main chain. Molecules contained only one hydrophilic and one hydrophobic fragment linked by a covalent bond. This facilitated the self-organization of macromolecules into micelles in aqueous media. The critical micelle concentration and its dependence on the molecular weight of the diblock copolymers and the length of the hydrophobic radical were determined
