1. (4 points) The following parameters were determined experimentally for the bulk polymerization of styrene at 60C and with a density of 0.9 g/cm: kp= 276 L (mol s)', kta = 4.2 x 107 L (mol s)-', kte = 0. For the benzoyl peroxide initiator, the ka = 2.10 x 10-6 s?. Determine (a) the necessary concentration of initiator to reach 100 kg/mol assuming 50% initiator efficiency and (b) the rate of polymerization for these conditions
