Original Khojo Papers practice question — not from a past board paper.
Answer
In addition polymerisation the monomers, which must be unsaturated, simply add to one another with no loss of any molecule, as in the formation of polythene from ethene. In condensation polymerisation the monomers combine with the elimination of a small molecule such as water, as in the formation of nylon 6,6 from a diamine and a dicarboxylic acid.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
The repeating unit of an addition polymer has the same formula as its monomer; that of a condensation polymer does not.
