Organic molecules are able to combine to form very long chains
A repeating unit is called a monomer, and are the molecules which make up the polymer.
- Occur under high temperature and pressure
- Double bonds in monomers “flick out” to connect two molecules.
- Formed by the rearrangement of double bonds
- Occur when a dialcohol combines with a dicarboxylic acid (hence forming an ester)
- Or when a monomer containing an alcohol and a carboxylic acid bonds with another of the same molecule
- This type is called a polyester
- Water is formed
- Special type of condensation polymer
- Water is also formed
- Occurs when COOH group bonds with NH2 group.
- Bond formed is called peptide or amide bond.
