  1. 1. POLYMERS
  2. 2. POLYMERS
  3. 3. <ul><li>polymers – molecules where many subunits are linked in a long chain </li></ul><ul><li>monomers – subunits which can be combined to produce a polymer </li></ul><ul><li>polymerization – the process of creating polymers by reacting monomers together </li></ul>POLYMERS
  4. 4. <ul><li>Two main reactions tend to be used to produce polymers: </li></ul><ul><li>addition reactions </li></ul><ul><li>condensation reactions </li></ul>POLYMERS
