Required Training	Required PPE
UC Lab Safety Fundamentals	Lab coat, safety glasses/goggles, nitrile gloves

Equipment	Chemicals
250 mL beaker	Solution 1 – 50 mL 0.5M Hexamethylenediamine in 0.5 NaOH (3.0g Hexamethylenediamine and 1.0 g NaOH in 50 mL DI water)
Stirring rod
Hooked spatula	Solution 2 – 50 mL 0.2 Sebacoyl Chloride in hexane (2.14 mL Sebacoyl Chloride in 50 mL in hexane)
Wash bottle

Procedure:

Wearing gloves, place Solution 1 in the beaker. Food coloring can be added to this layer to enhance visibility of the interface.
Slowly pour Solution 2 down the side of the beaker to get 2 layers. Try not to agitate the interface.
With the hooked spatula, grasp the polymer film at the interface and pull up from the center of the beaker.
Wrap the polymer thread around the stirring rod.
Continue to spool the thread around the stirring rod by slowly turning the stirring rod.
Wash the nylon thoroughly with water before handling.

Discussion:

N/A

Hazards:

Hexane is flammable, so keep this away from open flames and ignition sources. Solution 1 is basic, so if any comes in contact with skin, wash with copious water.

SOP:

Acutely Toxic – Sebacoyl Chloride

Carcinogen – Hexane

Corrosive – Sodium Hydroxide

Reproductive Hazard – Hexane,

Disposal (by Storeroom)

Thoroughly mix the remaining solution and remove any solid nylon that is produced. Wash the nylon and discard in a solid waste container. Discard remaining liquid in a solvent waste container.
