  • Polymers
    • Addition polymer
      • Formed by joining small alkene together
      • individual, small molecules = monomers
      • Repeat Units: C=C
      • Finding monomer of a polymer chain
        • 1. Find the repeat unit.             2. Then find the monomer by removing the central single C-C to C=C
    • Condensationpolymer
      • Involves two different types of monomer and a loss of small molecules such as water
      • Examples: Polyester with an ester link -COO and Polyamide with an amide link -CONH
      • Polyamide
        • react dicarboxylic acid and diamine
        • small loss of water molecules
      • Polyester
        • react dicarboxylic acid with hydroxyl group
        • small loss of water molecules
  • Hydrolysis of polyesters and polyamides
    • Reversing the reaction by adding water

          • small loss of water molecules
    • Polyamide hydrolyses more easily with an acid to form a dicarboxylic acid and a diammonium salt
    • polyeter hydrolyses more easily with a base forming a metal salt of the dicarboxylic acid and -diol
