In normal free radical processes with added initiator, the polymerization rate and kinetic chain length are proportional to the first power of monomer concentration. What would be the effect of monomer concentration on rate and chain length in the thermal polymerization of styrene (which involves no initiator)? Derive a kinetics expression to show this.Assume that initiation is based on the following equation: M + M -> 2 M. (radical in the product).

For polymerization of styrene in tetrahydrofuran at 25°C using sodium naphthalide initiator, the rate coefficient for propagation is 550 dm^3 mol^-1 s^-1. If the initial mass concentration of styrene is 156 g dm^-3 and that of sodium naphthalide is 3.02x10^-2 g dm^-3, calculate the initial rate of polymerization and, for complete converison of the styrene, the number-average molar mass of polystyrene formed. Comment upon the expected value of molar mass dispersity (Mw/Mn) and the stereoregularity of the polystyrene produced. Assume:...
