Initial radical concentration, Chemistry

Assignment Help:

(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.
