Round 6: Tossup 12

Heeger, MacDiarmid, and Shirakawa shared the 2000 Nobel Prize in Chemistry for developing the “conductive” type of these molecules. The degree of forming these molecules equals one over one minus the extent of the reaction according to the Carothers (“ker-OTHERS”) equation. Olefin-based examples of these molecules can be formed using a catalyst named for (*) Ziegler (10[1])and Natta. These molecules are usually represented by a chemical formula inside parentheses (10[1])with a subscript n. These molecules are formed via step-growth and chain-growth mechanisms. For 10 points, kevlar and nylon are examples of what (10[1])type of molecules made of monomer subunits? ■END■
