Condensation Polymerization (Nylon 6,6)

nH₂N(CH₂)₆NH₂ + nHOOC(CH₂)₄COOH → nylon 6,6 + nH₂O

Aperçu

Hexamethylenediamine reacts with adipic acid to form nylon 6,6 through condensation polymerization, releasing water. Each amide bond formed links the monomers into a long chain. The nylon rope trick demonstration draws a continuous nylon thread from the interface of two immiscible solutions.
