9.3 Polymers

Cards (22)

  • What are polymers made up of?
    Monomers
  • Match the monomer with its polymer and use:
    Amino acids ↔️ Proteins
    Nucleotides ↔️ DNA, RNA
    Sugars ↔️ Carbohydrates
  • In condensation polymerization, a small molecule such as water is eliminated
  • Steps in the process of polymerisation
    1️⃣ Initiation
    2️⃣ Propagation
    3️⃣ Termination
  • The termination step in polymerisation stops the chain reaction either naturally or by a terminating agent.
    True
  • Addition polymerisation uses alkenes as monomers, while condensation polymerisation uses bifunctional monomers
  • The variety of monomers allows for the creation of polymers with different characteristics, such as plastics, rubbers, and proteins.

    True
  • In medicine, polyurethane is used for creating catheters and tubing
  • Polymers are formed through a process called polymerization
  • Arrange the steps of polymerization in the correct order:
    1️⃣ Initiation
    2️⃣ Propagation
    3️⃣ Termination
  • Addition polymerization results in polymers with repeating units and functional groups
    False
  • Match the type of polymerisation with its characteristic:
    Addition Polymerisation ↔️ Monomers join directly
    Condensation Polymerisation ↔️ Monomers join with loss of water
  • The ability to synthesize polymers enables their use in drug delivery systems
  • What happens to polymers during chemical recycling?
    Broken into chemical components
  • Polymers can be synthesized for specific needs

    True
  • What are the two main types of polymerization?
    Addition and condensation
  • What is the process called where monomers join to form polymers?
    Polymerisation
  • During propagation, monomers link together one by one to form long polymer chains
  • What small molecule is eliminated during condensation polymerisation?
    Water
  • What is one key property of polymers due to their large molecular size?
    High strength
  • Where is polypropylene commonly used?
    Car parts
  • Non-biodegradable polymers can persist in the environment for long periods, causing pollution.

    True
