Examples of Synthetic Polymers - Plastics


  1. Plastics are light, strong and do not react with any chemical substances, like acids and alkalis.
  2. They can be made into many shapes and sizes.
  3. They are also good insulators of heat and electricity.


Examples of Plastics:

Polythene (polyethylene)

Structure

Monomer: Ethene
Produced by polymerisation: Addition
Uses: Plastic bags containers and cups
Advantages:  light and strong


Polyvinyl chloride or PVC (polychloroethene)

Structure

Monomer: Chloroethene
Produced by polymerisation: Addition
Uses: Raincoat, Pipes to insulate electric wires
Advantages: can be coloured; heat resistant


Polystyrene (polyphenylethene)

Structure

Monomer: Phenylethene
Produced by polymerisation: Addition
Uses: Packaging materials,  children toys, ball-point pens, as heat and electric insulators
Advantages: light and strong


Perspex (polymethyl 2-methyl propenoate)

Structure

Monomer: Methyl-2-methylpropenoate
Produced by polymerisation: Addition
Uses: Aeroplane window panes,  Lenses, car lamp covers
Advantages: light, strong, translucent, stable towards sunlight


Polypropene

Structure

Monomer: Propene
Produced by polymerisation: Addition
Uses: Plastics, Bottles, plastic tables and chairs
Advantages: strong and light


Teflon (polytetrafluoroethene or PTFE)

Structure

Monomer: Tetrafluoroethene
Produced by polymerisation: Addition
Uses: To make non-sticky pots and pans
Advantages: hard, can withstand high temperatures and corrosives chemicals

  1. I was astonished looking at the chemical conversion of chloroethene to polyvinyl chloride. PVC compound just knows it, but the drastic effects are threatening. It’s better to stop using it.
