- Polymers
- Addition polymer
- Formed by joining small alkene together
- individual, small molecules = monomers
- Repeat Units: C=C
- Finding monomer of a polymer chain
- 1. Find the repeat unit. 2. Then find the monomer by removing the central single C-C to C=C
- Condensationpolymer
- Involves two different types of monomer and a loss of small molecules such as water
- Examples: Polyester with an ester link -COO and Polyamide with an amide link -CONH
- Polyamide
- react dicarboxylic acid and diamine
- small loss of water molecules
- Polyester
- react dicarboxylic acid with hydroxyl group
- small loss of water molecules
- Addition polymer
- Hydrolysis of polyesters and polyamides
- Reversing the reaction by adding water

- Addition polymer
- Polyamide hydrolyses more easily with an acid to form a dicarboxylic acid and a diammonium salt
- polyeter hydrolyses more easily with a base forming a metal salt of the dicarboxylic acid and -diol
