The answer is 3. Polyester.
Teflon, PVC, and neoprene are all addition polymers, while polyester is a condensation polymer.
- Teflon is a polymer of tetrafluoroethylene. It is a non-stick material that is often used in cookware and other applications where a non-stick surface is required. Teflon is an addition polymer because it is formed by the addition of tetrafluoroethylene molecules to each other.
- PVC is a polymer of vinyl chloride. It is a hard, rigid material that is often used in pipes and other applications where a strong, durable material is required. PVC is an addition polymer because it is formed by the addition of vinyl chloride molecules to each other.
- Neoprene is a polymer of chloroprene. It is a synthetic rubber that is often used in gloves and other applications where a flexible, waterproof material is required. Neoprene is an addition polymer because it is formed by the addition of chloroprene molecules to each other.
- Polyester is a polymer of ethylene glycol and terephthalic acid. It is a strong, lightweight material that is often used in clothing and textiles. Polyester is a condensation polymer because it is formed by the condensation of ethylene glycol and terephthalic acid molecules.
In a condensation polymer, two monomers react with each other to form a polymer and a small molecule, such as water. In an addition polymer, monomers add to each other to form a polymer. |
