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.

Materials :1. Hexamethylenediamine [1 ml]2. Sebacoyl chloride [1 ml]3. Hexane[25 ml]4. NaOH [1-2 palettes]5. Water[20ml]6. Beakers7. Glass stirring rod

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.

7. As shown in figure….

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

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

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.
