Schulz. G. V., Harborth G [Markromol. Chem., 1947 1, 106, published by Huthig and Wepf Verlag Basel] reported the following data for polymerization of methyl methacrylate in benzene at 50 degree C using the thermal decomposition of 0.0413 M benzoyl peroxide for initiation. (a) Show that these data are in accord with (35). (b) Assuming that the efficiency of initiation is independent of temperature, estimate E_ - 1/2 E_i + 1/2 E_i from these data. (c) Using data given in this chapter, evaluate the activation energy for the decomposition of benzoyl peroxide. (d) Explain the effects of monomer concentration and temperature on DP.
