| Abstract: | Polystyrene containing t-butyl nitroxide groups was prepared via polymer-analogous reactions and characterized by ESR measurements. Polymerizations of MMA and styrene initiated by AIBN at 50° have been investigated in the presence of the polymeric radical samples. A definite inhibiting effect was observed without retardation of the polymerization of either monomer. A linear relationship was found between the concentration of the polymeric inhibitor and the inhibition period. |
