How can you differentiate between addition and condensation polymerization ? |
|
Answer» Solution :Addition polymerization : In this type of polymerization , a large number of molecules of the same or different monomers simply add to one ANOTHER leading of the formation of a macromolecule. Addition polymerization generally occurs among molecules containing double and triple bonds. For example , formation of polythene from ethene and PAN from acrylonitrile, etc. Condensation polymerization : In this tpye of polymerization. two or more bifunctional molecules undergo a series of indepedent condensation reactions USUALLY with the elimination of simple molecules like water , alcohol , ammonia , carbon dioxide , hydrogen CHLORIDE , etc. to form a macromolecule, For example , nylon 6,6 is a condensation polymer of HEXAMETHYLENEDIAMINE and adipic acid formed by elimination of water molecules. |
