Addition polymerisation

    Cards (15)

    • What type of polymers are made using alkenes?
      Addition polymers
    • What feature characterizes alkenes?
      Presence of a carbon-carbon double bond
    • Why are alkenes considered unsaturated?
      They contain a carbon-carbon double bond
    • What happens to the double bond in alkenes under the right conditions?
      It can break to form new bonds
    • How can the reaction of ethene molecules be represented?
      By showing monomers on the left and polymer on the right
    • What is a repeating unit in a polymer?
      A group of atoms repeated throughout the polymer
    • How many carbons and hydrogens are in the repeating unit of ethene?
      Two carbons and four hydrogens
    • How should the bonds of the monomer be drawn?
      Facing up and down
    • What do the empty bonds in the repeating unit represent?
      Connections to other monomers
    • What does 'n' represent in polymerization equations?
      The number of repeating units
    • If n is 10, how many ethene molecules are there?
      Ten ethene molecules
