Popis:	The specific features of synthesis of polystyrene, as well as random and block styrene-acrylonitrile and styrene-methyl methacrylate copolymers, in the presence of some alicyclic amines were studied. It was found that chain length regulators are not only amines themselves, but also nitroxyl radicals formed in situ as a result of oxidation of amines by benzoyl peroxide, which acts simultaneously as the initiator of radical polymerization and an oxidant. It was shown that secondary amine-peroxide binary compositions are able to control most effectively the kinetic parameters of polymerization and the molecular-mass characteristics of formed macromolecules.
