Prediction and measurement of propagation rate coefficients in terpolymerization reactions. Part 2. Experimental study

The terpolymerization propagation kinetics of p-methoxystyrene, styrene and methyl methacrylate were investigated using pulsed-laser polymerization. I n this work we used parameters obtained from the constituent copolymerizati on reactions to predict the propagation rate coefficients expected on the b asis of an implicit penultimate unit model. In other words the model predic tion was made with no adjustable parameters. We showed that this model coul d predict the experimental propagation rate coefficient values in this terp olymerization. This provides strong evidence for the validity of the implic it penultimate unit model.
