DEFINITION

Classification: 516/908

The compound contains repeating -(OC nH 2n)- (i.e., repeating unsubstituted oxyalkylene):

A collection of art under cross-reference art collection 907 in which the colloid system making or stabilizing agent* which contains an organic* compound which contains phosphorus also contains repeating -(OC nH 2n)- (i.e., repeating unsubstituted oxyalkylene).

(1) Note. "Repeating -(OC nH 2n)-" means 2 or more, bonded directly to each other. Thus, this subclass requires at least two ether linkages; monoether derivatives are located elsewhere.

SEE OR SEARCH THIS CLASS, SUBCLASS:

1+, for colloid system having a continuous gas or vapor phase (such as, smoke, fog, aerosol, cloud, mist) or method of making or stabilizing which employs as an agent* an organic* compound which contains phosphorus and also contains repeating -(OC nH 2n)- (i.e., repeating unsubstituted oxyalkylene).

13, for colloid system of continuous liquid phase and a discontinuous gas or vapor phase (i.e., foam) or method of making or stabilizing which employs as an agent* an organic* compound which contains phosphorus and also contains repeating -(OC nH 2n)- (i.e., repeating unsubstituted oxyalkylene).

24, for colloid system of primarily organic* continuous liquid phase and a discontinuous phase primarily inorganic* liquid (e.g., water-in-oil emulsion) or method of making or stabilizing which employs as an agent* an organic* compound which contains phosphorus and also contains repeating -(OC nH 2n)- (i.e., repeating unsubstituted oxyalkylene).

31+, for colloid system of primarily organic* continuous liquid phase and a discontinuous phase primarily solid or semisolid material* or method of making or stabilizing which employs as an agent* an organic* compound which contains phosphorus and also contains repeating -(OC nH 2n)- (i.e., repeating unsubstituted oxyalkylene). 40, for colloid system of aqueous continuous liquid phase and a discontinuous phase primarily bituminous or method of making or stabilizing which employs as an agent* an organic* compound which contains phosphorus and also contains repeating -(OC nH 2n)- (i.e., repeating unsubstituted oxyalkylene).

57, for colloid system of aqueous continuous liquid phase and a discontinuous phase primarily organic* liquid (e.g., oil-in-water emulsion) or method of making or stabilizing which employs as an agent* an organic* compound which contains phosphorus and also contains repeating -(OC nH 2n)- (i.e., repeating unsubstituted oxyalkylene).

77+, for colloid system of aqueous continuous liquid phase and a discontinuous phase primarily (non-bituminous) solid (e.g., water based suspensions, dispersions, sols) or method of making or stabilizing which employs as an agent* an organic* compound which contains phosphorus and also contains repeating -(OC nH 2n)- (i.e., repeating unsubstituted oxyalkylene).

98+, for subject matter relating to colloid system having a continuous or semicontinuous solid phase (i.e., systems which exhibit plasticity, elasticity, or rigidity), such as gel, paste, gelled emulsion, floc.

113+, for subject matter relating to breaking (resolving) or inhibiting a colloid system which employs as an agent* an organic* compound which contains Phosphorus and also contains repeating -(OC nH 2n)- (i.e., repeating unsubstituted oxyalkylene).
