| Ionic Polymerization | Free - Radical |
|---|---|
| Ionic polymerization is a chain polymerization in which the center contains ions and ion pairs. | Polymerizations created by adding free-radical building components are known as free radical polymerizations. |
| Ionic polymerization requires less activation energy than radical polymerization. | Initiators and co-initiators are used in free radical polymerization. |
| It's an alternative to polymerization by free radicals. | It's the only method to get diverse polymers and composite materials. |
