1 Answer

Answer :

Thermoplastics
Thermosetting
They can be repeated softened by heat and hardened on cooling
Once hardened and set they do not softened with application of heat
They are formed by addition polymerization only 
They are formed by condensation polymerization
They consist of long chain linear polymers
They have three dimensional network structure 
They are usually soft, weak and less brittle
They are usually hard, strong and more brittle 
They are usually soluble in some organic solvents
They are insoluble in almost all organic solvents
These can be repeatedly used and have resale value
They cannot reused and do not have resale value.
They cannot be used at higher temperature as they will tends to soft under heat 
They can be used at comparatively higher temperature without damage.
