402 Carraher’s Polymer Chemistry

3. What would you estimate the solubility parameters of silicones to be?
4. Sodium silicate is water soluble (forming water glass), but silicones are water repellents. Explain
the difference.
5. How might you polymerize an aqueous solution of sodium silicate?
6. How might you explain the good thermal stability of silicones?
7. Show the repeat unit for polydiethylsiloxane.
8. What are the reactants used to make phosphazenes?
9. Why would you predict that the chloro groups in phosphonitrilic polymers would be attacked
by water?

10. Which phosphazene would be more flexible—one made by reaction of poly(phosphonitrilic

chloride) with (a) sodium trifluoroethoxide or (b) sodium trifl uorobutoxide?
11. Show the structure of borazole.
12. Since tin-containing organometallic polymers are used in marine antifouling coatings, what
would by predict about their water resistance?
13. In addition to high cost, name another disadvantage of coordination polymers.
14. What is the ceiling temperature of sulfur nitride polymers?
15. What are the main uses of tin-containing polymers?
16. What is the basis for many of the electrical and optical applications of boron-containing
polymers?
17. Why is there interest in the synthesis and study of metal-containing polymers?
18. What are some attractive features of polysiloxanes?
19. Name two biological polymers that contain metals and which are important to life.
20. What is a main difference between ionic and covalent bonds remembering that most bonds have
both characteristics involved in them?
