Examples are polyamides, made by reacting a diacid with a diamine, and polyesters, made by reacting a diacid with a diol (a diol is a molecule containing two terminal OH groups).
The synthesis of Nylon 66 was demonstrated in class, using a solution of adipoyl chloride (an activated form of adipic acid) in hexane and hexanediamine in water.
Students will view the nylon rope demonstration to be introduced to polymer synthesis. They will then perform an inquiry investigation of organic synthesis by mixing various carboxylic acids with alcohols to create esters. Depending on the mixture between the acids and alcohols, different smells will be produced. The class will then come together and discuss the purpose of the lab and the results obtained.
