Which from following polymers is obtained by condensation polymerisation method?

Step-by-step solution

Condensation polymerization produces polymers through monomer reactions that eliminate small molecules such as water, methanol, or hydrogen chloride as byproducts. Polythene results from addition polymerization of ethylene monomers, with no small molecules eliminated. Nylon 6,6 forms via condensation polymerization between hexamethylenediamine H₂ N-(CH₂ )₆ -NH₂ and adipic acid HOOC-(CH₂ )₄ -COOH , with water molecules eliminated during amide bond formation. Polyacrylonitrile and Teflon both derive from addition pol
