DEFINITION

Classification: 106/162.6

With cellulose xanthate or viscose (i.e., mixture of cellulose xanthate or viscose and a carbohydrate material which is other than cellulose xanthate or viscose):

(under subclass 162.1) Compositions which contain cellulose xanthate or viscose in addition to the carbohydrate or derivative whereby the carbohydrate or derivative is not cellulose xanthate or viscose.

(1) Note. Cellulose xanthate or viscose is a cellulose derivative with the group: [figure]

(2) Note. The viscose process is based on the reaction of carbon disulfide with the sodium salt of cellulose to yield a xanthate, which forms a viscous colloidal solution in dilute aqueous alkali. [figure]
