Abstract: | The kinetic features of radical polymerization of styrene in the presence of primary and secondary aliphatic amines combined
with benzoyl peroxide and the molecular-mass characteristics of the resulting polymers were studied. In the presence of peroxide
initiators, aliphatic amines, as potential sources of stable aminoxyl radicals, provide the synthesis of polystyrene with
a controlled molecular mass without gel effect at a relatively high rate.
