Abstract: In this paper, the influence of 1,4-dihydropyridines on the polymerization of styrene and methyl methacrylate initiated by AI BN and BP was studied. 1,4-Dihydropyridines contained substituents in positions 2,6 and 3,5 and in some cases also in position 4. It was found that during the polymerization of both monomers initiated by AI BN substituted 1,4-dihydropyridines have no influence on the polymerization kinetics and the relative molecular mass of polymers obtained. During the polymerization initiated by BP, 1,4-dihy­dropyridines influence the polymerization rate of both monomers because a reaction between BP and NH group takes place. The acceleration or re­ tardation of the polymerization is the final effect of this reaction. This effect depends on the reactivity of vinyl monomer. During the oxidation of styrene initiated by AI BN in the presence of 1,4-dihydropyridines retardation was observed.
