  1. 8.1 Condensation Polymers 8.1.1 Starch LO: I know the structure of starch.

  2. Starch is a condensation polymer formed by joining molecules together. glucose Each monomer in a condensation polymer must have at least functional groups. two LO: I know the structure of starch.

  3. 8.1.2 Polyesters LO: I know the structure of a polyester.

  4. alcohol An ester is formed when an reacts with a acid. carboxylic The monomers used to make a polyester are: • An alcohol with two groups (diol). hydroxyl • An acid with two groups (diacid). carboxyl LO: I know the structure of a polyester.

  5. 8.1.3 Polyamide LO: I know the structure of a polyamide.

  6. O H H N C N H H H H H C C N H H H amine An amide is formed when an reacts with a carboxylic acid. NH2 An amine is a molecule containing an amino group (): For example, ethylamine: CH3CH2NH2 The molecules react to form an amide link: LO: I know the structure of a polyamide.

  7. is a polyamide. • An amine with two groups (diamine). amino The monomers used to make a polyamide are: • An acid with two groups (diacid). carboxyl Nylon LO: I know the structure of a polyamide.
