Find the main difference between then :
(i) Thermoplastic polymers
(ii) Thermosetting polymer

Explanation

Condensation polymerisation : In this type polymersation , two or more bifunctional molecules undergo a series of independent condensation reactions with the elimination of simple molecules such as water , alcohol , hydrigen chloride , etc . To form a macromolecule. For example , nylon 6,6.
Addition polymerisation : In this type of polymerisation , the polymers are formed by the repeated addition of monomer molecules possessing double or triple bonds . For example, formation of polythene from ethene.
