- ... 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. ...

- ... The soluble proteins isolated from normal wools differing widely in geographical origin, fineness, and breed show the same behavior in ultracentrifugation and diffusion. The wool protein, made soluble in aqueous 10M urea by reduction, has a sedimentation constant ap proaching 1.2 S at zero protein concentration, referred to water at 20°C. In the presence of 0.2N lithium chloride the limiting sedim ...
