Notes

(1)In this subclass, the following term is used with the meaning indicated:

 –"rubber" includes:

 (a)natural or conjugated diene rubbers;

 (b)rubber in general (for a specific rubber, other than a natural rubber or a conjugated diene rubber, see the group provided for compositions of such macromolecular compounds).  [2]

(2)In this subclass:

 (a)compositions are classified according to the mutual proportions by weight of only the macromolecular constituents;  [2]

 (b)compositions are classified according to the macromolecular constituent or constituents present in the highest proportion; if all these constituents are present in equal proportions the composition is classified according to each of these constituents.  [2]

(3)In this subclass, it is desirable to add the indexing codes relating to additional macromolecular constituents of the composition. The indexing codes, which are chosen from the groups of this subclass, have the same numbers as the classification symbols, but a colon is used instead of the oblique stroke, and should be linked.  [2]

(4)This subclass constitutes an indexing scheme associated with subclass C08J, relating to the materials used. The indexing codes should be unlinked.  [5]

(5)Attention is drawn to Chapter IV of the Guide which sets the rules concerning the application and presentation of different types of indexing code.  [6]
