Synthetic Polymers
Gbogbo ọrọ náà
Plastics are everywhere - packaging, clothing, electronics, medical equipment. Almost all of them are synthetic polymers, giant molecules built by joining thousands of small monomer molecules together.
In this lesson you will learn what monomers and polymers are, how addition polymerisation works, how to draw repeat units from monomers and vice versa, and the environmental problems that come from disposing of these incredibly durable materials.
Ebumnobi
- Know that an addition polymer is formed by joining up many small molecules called monomers
- Understand how to draw the repeat unit of an addition polymer
- Understand how to deduce the structure of a monomer from the repeat unit of an addition polymer and vice versa
- Explain problems in the disposal of addition polymers, including their inertness and the production of toxic gases when burned
