Give two differences between an addition polymer and a condensation polymer.
Addition polymer | Condensation polymer |
1. Addition polymerisation involves one monomer. | 1. Condenstion polymerisation involves two monomers. |
2. The monomers are unsaturated compounds. | 2. The monomers contain twon functional groups. |
3. No loss of any molecules. | Small molecules usually water is lost. |
