Nylon Rope Trick
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. The nylon rope trick typically makes use of a water solution of an aliphatic diamine with a solution of an aliphatic diacid chloride in a solvent that does not dissolve in water, yielding a synthetic polyamide of the nylon-type. Nylon 610 is commonly used, in which hexamethylene diamine is dissolved in water to a concentration of about 0.40 moles / deciliter. A solution of sebacoyl chloride in cyclohexane (0.15 moles / deciliter concentration) is then layered on top of the water solution, the reaction typically being conducted in a beaker. The solution is not agitated; instead the nylon 610 polymer forms as a flexible film at the interface of the water and cyclohexane layers, in an example of an interfacial polymerizatio ...
