• What are polymers?


  Polymers are large molecules made up of repeating subunits called monomers.
• How many monomers make a polymer?

  1000
• What are examples of NATURAL polymers?

  Cellulose, starch, proteins, DNA, silk, cotton & wool.
• What are examples of SYNTHETIC polymers?

  Polyethylene, polypropylene, PVC, nylon, polyester.
• What is a high density polyethylene?

  a type of plastic commonly used for making bottles, toys & plastic bags.
• What is a low density polyethylene?

  Another type of plastic that is more flexible.
• What is polymerisation?


  Polymerisation is the reaction of monomer molecules to form long chain polymer molecules.
• What are monomers?


  Monomers are small molecules that can join together to form larger molecules called polymers.
• What is addition polymerisation?

  Addition polymerisation is the process of repeated addition of monomers that possess double or triple bonds to form polymers.
• What is condensation polymerisation?

  Condensation polymerization occurs when two small molecules, called monomers, react with each other and release a small molecule like water or alcohol. The reaction causes the monomers to bond together, forming a polymer.
