GCSE Chemistry - What is a Polymer? Polymers / Monomers / Their Properties Explained #23

The video tutorial covers the structure and bonding of polymers, explaining how they are composed of repeating units called monomers. It illustrates the formation of polymer chains using polypropene as an example. The tutorial also discusses how to identify repeating units and draw them, emphasizing the use of curved brackets and the letter 'N' to denote the number of units. Additionally, it explains the melting and boiling points of polymers, highlighting the role of intermolecular forces. Finally, it introduces different types of polymers, such as addition and condensation polymers.
