Chapter 20 - 1 Polymers
Right side
1. How many bonds can carbon form?
    A. 4
2. Carbon atoms can form
    A.  Fig. 2, pg. 633
        1. Straight chains
        2. Rings
        3. Branches
3. Carbon can form many compounds
    A.  Called the “backbone”
4. Polymers   
    A. form when chemical bonds link large numbers of monomers in a repeating pattern
        1.  Monomer- (mono = one)
        *draw the 2 types monomers from fig. 3
5. Natural polymers
    A.  Plant
        1.  Cellulose
    B.  Animal
        1.  Fingernails
        2.  Muscles
        3.  Spider webs
        3.  Wool
        4. Hair
6. Synthetic
    A. plastics
7. Composites
    A. chemists can make new materials from combining useful properties form two or more polymers
        1.  Example – wood
            a.  Combination of cellulose and lignin
8. Too many polymers
    A. synthetic polymers become a trash problem
    B. fig. 7, pg.639
    C. Every problem can be solved = recycle old polymers to make new polymers
