| Addition polymerization | Condensation polymerization |
|---|---|
| The addition polymerization means that two monomers react with each other and no other small molecules are generated. The best example is polymerization of ethylene. |
The condensation polymerization, as a contrast, normally involves the generation of small molecule products. |
| It requires two like molecules. | It requires two unlike molecules. |
| Kinetic long linear chain reaction. | Intermolecular reaction. |
| Very fast reaction 10-2 – 10-6sec | Slow reaction takes hours and days to complete. |
| No by total. | By product it produced. |
| Polymer produced thermoplastic. | Chemo setting plastic produced. |
| Example: PVC, Teflon, Poly ethylene. | Example: Bakelite, Silicon, GRP, Polystyrene. |
