bonding in polymers

Cards (8)

  • Polymer
    Very large molecule made by joining together thousands of small identical molecules called monomers
  • Monomer
    Small identical molecule that polymers are made from, often alkene molecules
  • Monomer
    • Ethene
  • Forming a polymer
    Joining together thousands of monomer molecules
  • Polymer
    • Contains single carbon-carbon covalent bonds, unlike monomers which contain double carbon-carbon covalent bonds
    • Covalent bonds in polymers are extremely strong
  • Repeating unit
    Shorthand way to represent a polymer, shows a single carbon-carbon covalent bond with the bonds extending out on either side, and the letter 'm' indicating a large number of repeating units
  • Most polymers are solids at room temperature
  • Polymers have strong intermolecular forces of attraction between molecules

    It takes a lot of energy to break these forces, so polymers have a high melting point and are solids at room temperature
