  • What does the term "inert" mean when describing polymers?
    Not reactive or very slow to degrade.
  • What is a repeating unit?
    A section of a polymer chain that represents the pattern of the polymer.
  • Which monomers are used to make nylon?
    A dicarboxylic acid and a diamine.
  • What functional groups are involved in condensation polymerisation?
    Carboxylic acids and alcohols or amines.
  • What is condensation polymerisation?
    A reaction where monomers join to form a polymer with the elimination of a small molecule such as water or HCl.
  • What polymer is made from amino acids?
    Proteins.
  • Give an example of a natural polymer.
    Proteins or starch or cellulose.
  • What type of polymer is formed from alkenes?
    Addition polymer.
  • Why are polymers a problem for the environment?
    They are non-biodegradable and accumulate as waste.
  • Name one way to reduce polymer waste.
    Recycling or using biodegradable alternatives.
  • What is the difference between addition and condensation polymerisation?
    Addition uses alkenes and no by-product is formed; condensation uses monomers with functional groups and a small molecule like water is produced.
  • What is the name of the polymer formed from ethene?
    Poly(ethene) or polythene.
  • What type of bond is broken in the alkene during addition polymerisation?
    The double bond.
  • What small molecule is usually eliminated in condensation polymerisation?
    Water.
  • What does the polymer poly(chloroethene) contain?
    Chloroethene monomers (vinyl chloride).
  • What is a polymer?
    A long chain molecule made from repeating units called monomers.
  • What is the name of the polymer made from tetrafluoroethene?
    PTFE or poly(tetrafluoroethene).
  • What is addition polymerisation?
    A reaction where unsaturated monomers (alkenes) join to form a polymer without producing any other substance.
  • What is the name of the monomer that forms poly(propene)?
    Propene.
  • What is a monomer?
    A small molecule that can join with others to form a polymer.
