nylon 11 is a bulking agent used primarily in makeup preparations and in some moisturizers.
제조 방법
Nylon 11 is produced continuously by heating ro-aminoundecanoic acid at
200--220°C with continuous removal of water. The latter stages of the
reaction are conducted under reduced pressure in order to produce polymer
of high molecular weight. In addition to the formation of polymer, about
0.5% of the 12-membered ring lactam is produced by intramolecular
condensation but this is not normally removed since its presence has little
effect on the properties of the polymer.
