After this lesson, you should be able to:

• Explain the terms polymer, macromolecule, chain, monomer, functional groups
• Illustrate the reaction to produce a polymer by an addition reaction using the polymerization of ethene to produce polythene
• List some industrial uses of polythene
• Illustrate the reaction to produce a polymer by condensation reaction
• Identify the monomer used to produce a polymer from the structural formula
• Identify a polymer as the product of an addition or condensation polymerization reaction from its structural formula
