What thermoplastic and thermosetting polymers?

1.	What thermoplastic and thermosetting polymers?
Answer» Thermoplastics are linear polymers which can be repeatedly softened on heating and hardened on cooling and hence can be repeatedly used. Ex: polythene, polypropene etc. Thermosetting polymers are on the other hand permanently setting polymers. On heating, they harden and cant be softened again. Ex: bakelite, urea-formaldehyde resin.
