... Radical Polymerization as an Indicator Reaction for Determination of Organic Compounds M. K. Beklemishev, I. V. Nikolaev, and L. Yu. ... The effect of 26 model organic compounds on the polymerization rate has been studied. ... Effect on model compounds on VP and MMA polymerization. ... At low radical concentrations (i.e., in the case of MMA), a considerable fraction of radicals can be trapped by almost any model compound; most of these compounds will decrease the overall polymerization rate. ...

... For the auto-acceleration regime, the experimental data correspond to the kinetic equation wt = k [ P ] 1/2 t [ IO 4 ] - 1/2 t [TMB]0, where wt is the accumulation rate of the meriquinoid product (P) of TMB oxida- 4 ]t tion and [P]t and [ IO are the concentrations of product P and periodate, respectively, at time t. A radical chain mechanism was proposed; the mechanism explains the experimental kinetic equation and complies with the observed inhibiting effect of metal ions (Zn, Cd) in this reaction....
