Presentation transcript:

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

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.

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

An ester is formed when an reacts with a acid. alcohol 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.

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

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

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