Addition Polymers (T)

• What is meant by an addition polymer?

  Addition polymers are made by joining together thousands of small identical molecules called monomers.
• What are monomers?

  Monomers are small identical molecules that join together to form polymers.
• What is a repeating unit in the context of polymers?

  A repeating unit is a shorthand way of showing the structure of a polymer.
• What is the relationship between monomers and addition polymers?

  • Monomers are the building blocks of addition polymers.
  • Addition polymers are formed by joining together many monomers.
• What types of polymers are there?

  There are two types of polymers: addition polymers and condensation polymers.
• What type of monomers are used to form addition polymers?

  Alkenes are the monomers used to form addition polymers.
• What is the name of the polymer formed from the monomer ethene?

  The polymer formed from ethene is called polythene.
• How is the name of a polymer derived from its monomer?

  The name of the polymer is the word "poly" followed by the name of the monomer.
• What happens to the double bond in the monomer when it forms an addition polymer?

  The double bond in the monomer is converted to single bonds in the polymer.
• What is the significance of the letter 'N' in the repeating unit of a polymer?

  • 'N' represents a large number.
  • It indicates that the polymer consists of a large number of repeating units.
• What is a key characteristic of the repeating unit in addition polymers?

  The repeating unit has the same atoms as the monomer and does not contain a double bond.
• How would you represent the repeating unit for polythene?

  By taking two adjacent carbon atoms, drawing them with hydrogen atoms, placing brackets around them, and writing 'N' to the right.
• What is the polymer produced from the monomer chloroethene?

  The polymer produced is poly(chloroethene).
• How do you draw the repeating unit for the polymer produced from propene?

  Replace the double bond in propene with a single bond, draw bonds on either side of the carbon atoms, place brackets around it, and write 'N' on the right.
• What is the name of the polymer produced from propene?

  The polymer produced from propene is called polypropene.
