1. What is the equation describing the mole fraction of x-mer present in a polycondensation reaction at an extent of reaction p?
2. In a condensation polymerization between monomers containing A and B functional groups a 2% excess of groups B is used. What is the maximum degree of polymerization that can be achieved? (Assume r = 100/102).
3. If there had been exactly equal numbers of monomers used in the condensation reaction of
Question 2 what extent of reaction (p) would be necessary to achieve a number average degree of polymerization of 200? What would the weight average degree of polymerization of this sample be?
4. Consider the following plot showing kinetic data for a polyesterification.
Was this polymerization catalyzed by adding a strong acid? Why?
5. AIBN is used to initiate the polymerization of methylmethacrylate in benzene at 60°C and
