Popis:	The temperature dependence of the binary radical copolymerization constants has been investigated for stilbene with styrene and acenaphthylene in the temperature interval 70–140°. The difference between the activation energies and entropies has been determined as well as the ratio of preexponential factors for the rate constants of elementary steps of chain propagation. The influence of the steric effect on the addition of the stilbene monomer and radical during chain propagation has been demonstrated. The preexponential factors and steric factors have been estimated for rate constants of elementary propagation steps for the system stilbene-styrene.
