Thermoplastic and the thermosetting resins:
| Thermoplastic resins | Thermosetting resins |
|---|---|
| These are formed by addition of polymerisation. | These are formed by condensation polymerisation only. |
| They are long chain linear polymer with negligible cross links. | These have 3-dimensional network structure with number of cross links. |
| They have low molecular weight. | They have high molecular weight. |
| They are usually soft, weak and less brittle. | They are hard, strong and more brittle. |
| Monomer used in these is generally bifunctional. | Monomer used in these is of higher functionality. |
| They are soluble in some organic solvents. | Due to strong bonds and cross links, they are insoluble in almost all organic solvents. |
