2. Aim :
To prepare polymide, nylon 66
Introduction :
Nylons are some of the most important fibers
produced commercially. A lot of nylon produced ends
up clothes. But nylon can be more than just fibers. It is
also up as other everyday things likes ropes, tents,
airbags and toothbrush bristles. Nylon 66 lends itself well
to make 3D structural objects. Nylon 66 is also a popular
guitar nut material.

3. Materials :
1. Hexamethylenediamine [1 ml]
2. Sebacoyl chloride [1 ml]
3. Hexane[25 ml]
4. NaOH [1-2 palettes]
5. Water[20ml]
6. Beakers
7. Glass stirring rod

4. Procedure :
1. Take 1ml of sebacoyl chloride and 25ml of hexane
mix it a beaker.
2. In the other beaker take 20ml of water and mix 1ml of
hexamethylenediamine and one palette of NaOH.
3. Then wait for sometime till NaOH palettes are totally
dissolved in hexamethylenediamine solution.
4. After dissolving of it add the sebacoyl chloride
solution into hexamethylenediamine solution.
5. Then wait for sometime the solution turns to sticky
manner
6. Then by using glassrod slow rotate the rod and take
nylon 66 from it.

5. 7. As shown in figure….

6. 8. For the good apperence we added phenolphthalein
to the solution
9. then the solution changes colourless to pink because
of the presence of NaOH as shown in figure

7. 10. At last this is the Nylon 66…. As shown in figure

8. Conclusion :
Formed Nylon 66 can be extruded and
granulated at this point or directly spun into fibers
by extrusion through a spinneret and cooling to
form filaments.
