| titleOfInvention | Polyamide filaments and process for making same |
| abstract | Poly[bis(para - aminocyclohexyl)methaneazelamide] which may be used to make filaments (see Division B5) is prepared from the diamine and azelaic acid. In an example, the polymer is prepared in an autoclave from a 50% aqueous solution of the salt of bis-(para-aminocyclohexyl) methane and azelaic acid. The diamine consists of 70% trans-trans, 25% cis-trans and about 5% cis-cis isomers. As viscosity stabilizer, 17.5 millimoles of acetic acid are added for every mole of the polyamide salts. The salt solution is heated under 350 lbs. per sq. in. pressure for 2 hours while the temperature is raised to 285 DEG C. The pressure is then reduced to atmospheric while the temperature is raised to 315 DEG C. and the polymer held under these conditions for one hour. |
