Synthetic Polymers

  1. 1. Synthetic polymers
  2. 2. What are polymers ? <ul><li>Polymers are large molecules made up of many identical repeating sub-unit called monomers where are joined together by covalent bonds. </li></ul><ul><li>Monomers are joined into chains by a process of repeated linking known as polymerisation. </li></ul>
  3. 3. <ul><li>A polymer may consists more thousands of monomers. </li></ul><ul><li>Starch, cellulose, wood, protein, silk and natural rubber are some examplas of naturally occurrsing polymers </li></ul>
  4. 4. <ul><li>Synthetic polymers are mad-made polymers. </li></ul><ul><li>The monomers used are usually obtained from petroleum after going through the refining and cracking processes. </li></ul>
  5. 5. Monomers in synthetic polymers <ul><li>Water pipes </li></ul><ul><li>Artificial leather </li></ul><ul><li>Records </li></ul>Choroethene Polyvinyl chloride,PVC <ul><li>Piping </li></ul><ul><li>Bottle crates </li></ul><ul><li>Ropes </li></ul>Propene Polypropene <ul><li>Plastic bag </li></ul><ul><li>Plastic containers </li></ul><ul><li>Shoping bag </li></ul>Ethene Polythene Example Monomer Synthetic polymer

  7. 7. Should we continue using synthetic polymer ? IF IT BURNT , THEY GIVE OUT HARMFULL GASES DO NOT DACEY / CORRODE CAN CAUSE FLASH FLOODS VERY STABLE NOT EASILY BIODEGRADABLE CAN BE COLOURED CAUSE POLLUTION EASY TO SHAPED DIFFICULT TO DISPOSE RELATIVELY CHEAP DISAVANTAGE AVANTAGE
