So I am trying to calculate a homopolymer's theoretical molecular weight (Mn) if I have a 0.3mol% catalyst.  How do I go about trying to find the theoretical weight if this is a living polymerization?

a) If you have a living polymerization, when will it stop reacting?

b) If you only have one initiation event, how long will that chain get? If you have two initiation events, how long will your two chains get?

c) How many chains will you be starting with 0.3 mol% catalyst?

Im assuming that it will stop growing once all the monomer is consumed.  If you have 0.3mol% then this should have 30 repeating units.  If I had 0.1mol% this would give me 100 repeating units, correct?  If the MW of one repeating unit is 166 mol/g and you know how much monomer you add, couldn't you theoretically calculate molecular weight if it was a PDI of 1?

Sorry...if I had 1mol% I would have 100 repeating units, right??
