Nylon
- one molale part of hexamethylene diamene
(NH2 (CH2)6 NH2)
- one molale part of adipic acid (HOOC(CH2)4COOH)
- stir in deionized water at 70 degrees celcius
- precipitate the nylon salt from solution
- evaporate nylon salt to 80% salt and drop into autoclave
- add acetic acid and TioO2
- autoclave to 295 degrees celcius and 250 psi
- at 250 the instantaneous polymerization occurs resulting in a polymer of 15,000 to 18,000 desired molecular weight
- H2O is bled off quick to 0 psi over a 30 minute period
- keep autoclave to 0 psi for 30 minutes to settle molten polymer
- extrude nylon over a roll sprayed with water
- cut nylon riddon into strips
- blend patch with 5 other ones to obtain average molecular weight
