Two samples of polystyrene, samples A and B, were synthesised. A from the addition of n- butyl lithium to styrene in THF under a nitrogen atmosphere, and B from the addition of benzoyl peroxide to styrene under a nitrogen atmosphere respectively. 1. Of the two polymers produced (A and B) one had Ma = 12,000 and a polydispersity of 1.1 and one a Ma=11, 200 and a polydispersity of 1.7. Identify which set of molecular weight parameters corresponds to which polystyrene sample.
