The number-average molecular weight of a polystyrene is 500,000 g / mol. Compute the degree of polymerization. | Numerade

Consider the polymerization of styrene in toluene at 60°C initiated by di-t-butylperoxide for a solution containing 0.04 mol of initiator and 2 mol of monomer per liter. The initial rates of initiation, Ri, and propagation, Rp, are found to be 1.6 x 10^-10 M/s and 6.4 x 10^-7 M/s respectively, at 60°C. Calculate kai and kplkin. Assuming no chain transfer, calculate the initial kinetic chain length. Assuming only disproportionation and under the conditions stated, the transfer constant of styre
