(Anionic polymerization)

1. Determine the final number-average and weight-average chain lengths and molecular weights along with the extent of polymerization and polydispersity in an anionic polymerization for an initial monomer concentration of 2 M and for initiator concentrations of 1, 0.01, and 0.0001 M.
   
   
2. Calculate the radical concentration and polymer concentration as a function of time for j = 3, 7, 10 for the same monomer and initiator concentrations. k_i = , k_P = 100 dm³/mol/s.
   
   
3. Repeat (b) for the case
   
   
   
   and
   
   
   
   with k_i = 10 dm³/mol/s and K_i = 10^-8 mol/dm³.
