NYLON 11 Chemical Properties,Usage,Production

Uses

nylon 11 is a bulking agent used primarily in makeup preparations and in some moisturizers.

Preparation

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.

Definition

ChEBI: 11-Aminoundecanoic acid is a medium-chain fatty acid.
