Jun 18, 2012 · The reaction between hexamethylene diamine in water and sebacoyl chloride in hexane produced nylon 6:10 at the interface between the two liquids. This can be drawn off as a continuous fiber, with

Step 3: The "Rope-Trick" (controlling the reaction) Because step-growth polymerization is sensitive to the initial quantities of reactants, we can’t simply mix A and B into a solution and expect long molecules.

Nylon forms at the interface and can be pulled out as fast as it isproduced forming a long thread – the ‘nylon rope’. A solution of decanedioyl dichloride in cyclohexane is floated on an aqueous solutionof 1,6-diaminohexane.

Abstract: In step-growth polymerization, the molecular weight of the polymer chain builds up slowly and there is only one reaction mechanism for the formation of polymer. The distinct initiation, propagation, and termination steps of chain-growth polymerization are

Nylon is a polymer you can make yourself in the lab.A strand of nylon rope is pulled from the interface between two liquids. The demonstration sometimes is called the ‘nylon rope trick’ because you can pull a continuous rope of nylon from the liquid indefinitely. Close examination of the rope will reveal that is is a hollow polymer tube.

The nylon rope trick is a scientific demonstration that illustrates some of the fundamental chemical principles of step-growth polymerization and provides students and other observers with a hands-on demonstration of the preparation of a synthetic polymer.
