Answer
Condensation polymerization
Explanation
Polyamides are formed through condensation polymerization, where monomers react to eliminate small molecules, typically water, during the formation of the polymer.
Common mistake
Incorrect Monomer Identification
Students often confuse the monomers used in polyesters and polyamides, leading to incorrect repeating units.
Review the structures of common monomers like ethylene glycol and terephthalic acid for polyesters, and hexamethylenediamine and adipic acid for polyamides. Practice drawing their structures to reinforce understanding.
