Abstract
Stearamidomethylpyridinium chloride reacts with cellulosic hydroxyl groups to produce a stear amidomethyl ether of cellulose. Substitutions of 1 stearamidomethyl group per 150 anhydro glucose units have been obtained. The permanent water-repellency obtained on treatment of cotton fabrics with amidomethylpyridinium salts is due to this reaction.
