Aim: What is polymerization? QQ: What is the difference between complete and incomplete combustion? Do Now: What does the word polymer mean? Monomer: small, simple molecule Polymer: large molecules made up of smaller repeating units (monomers) Representing Polymers Difficult to represent using a molecular or structural formula… “n” means that the unit repeats indefinitely Natural Polymers DNA and RNA Starch Cellulose Proteins Synthetic Polymers Plastics Nylons Polystyrene Teflon Polymer Synthesis Addition Polymerization: unsaturated monomers undergo addition reactions with one another

Unformatted text preview: Must use alkenes or alkynes! Condensation Polymerization: monomers are joined by dehydration reactions Must have functional groups with “-OH’s” Conclusions Polymers are large molecules made up of smaller, simpler repeating units (monomers) Polymers occur naturally and can be produced synthetically Polymers can be made by: o Addition requires unsaturated hydrocarbon o Condensation removal of water molecule to link the monomers together...
