(a) Given the values below, Determine the concentration of benzoyl peroxide needed to prepare polystyrene with a number average molar mass of 400,000 by bulk free radical polymerisation at 60°C, suppose all termination is by combination.
f = 0.6
kd=2×10-6 s-1
kp= 341 M-1 s-1
kt=4×107 M-1s-1
density of styrene = 880 kg m-3
(b) Determine the initial radical concentration and initial rate of polymerisation for this reaction.
