DEFINITION

Classification: 106/162.7

With cellulose ester or salt thereof (i.e., mixture of (A) a cellulose ester or salt thereof and (B) a carbohydrate material which is other than cellulose ester or salt of the same acid as in (A) differing only in the degree of esterification):

(under subclass 162.1) Compositions which contain (A) a cellulose ester or salt thereof in addition to (B) the

carbohydrate or derivative thereof whereby the carbohydrate or derivative can not be a cellulose ester or salt of the same acid as in (A) differing only in the degree of esterification.

(1) Note. See this class, subclass 168.01 for definition of cellulose ester or salt thereof.

(2) Note. This subclass provides for compositions containing both a and b as defined below:

(a)

cellulose ester such as: (1) cellulose ester of a single acid (e.g., cellulose acetate, cellulose propionate, etc.), (2) cellulose ester of mixed acids (e.g., cellulose butyrate propionate, cellulose propionate isobutyrate, etc.), or (3) mixture of cellulose esters of the same acid differ only in the degree of esterification (e.g., pyroxylin - mixture of cellulose tetranitrate and cellulose trinitrate, mixture of cellulose acetate and cellulose triacetate, etc.), and

(b)

carbohydrate or derivative. SEE OR SEARCH THIS CLASS, SUBCLASS:

162.5, 162.6, 162.8, and 162.9, for compositions containing carbohydrate or derivative and lignocellulosic material, cellulose xanthate, cellulose ether or salt, or cellulosic material.

162.71, for compositions containing cellulose ester (e.g., cellulose nitrate, cellulose acetate, etc.) and a cellulosic material (e.g., carboxymethyl cellulose, ethyl cellulose, etc.).

162.72, for compositions containing two or more different cellulose esters (e.g., cellulose nitrate and cellulose acetate, cellulose propionate and cellulose acetate, cellulose propionate and cellulose propionate isobutyrate, etc.).

169.01+, for compositions containing pyroxylin as the only carbohydrate or derivative and the only cellulose ester or derivative.
