8. What are the important features of chain-growth and step-growth polymerizations. Explain the
difference between the two? Can you suggest an analytical procedure to determine by what
mechanism a particular polymerization reaction takes place?
9. What is the DP of polystyrene with molecular weight of 104,000 and poly(vinyl chloride) with
molecular weight of 63,000?
10. Explain the differences between thermosetting and thermoplastic polymers and define gel point.
How would you determine the gel point of a thermoset polymer?
11. Give the definitions of oligomer, telomer, and telechelic polymers.
12. What is a dendrimer polymer and what is a rotaxane polymer?
13. Illustrate three chain-growth polymers and three step-growth polymers.
