 WORKING-UP; GENERAL PROCESSES OF COMPOUNDING; AFTER-TREATMENT NOT COVERED BY SUBCLASSES C 08 B, C 08 C, C 08 F, C 08 G(mechanical aspects B 29; layered products, manufacture thereof B 32 B; treatment of macromolecular material specially adapted to enhance its filling properties in mortars, concrete or artificial stone C 04 B 16/04, C 04 B 18/20, C 04 B 20/00; treatment of textiles D 06) [2]
 

Notes

(1)

 This subclass covers processes, not covered by subclasses C 08 B to C 08 H, for treating polymers. [4]

(2)

 In this subclass, in the absence of an indication to the contrary, classification is made in the last appropriate place. [2]

(3)

 In this subclass, it is desirable to add the indexing codes of subclass C 08 L. The indexing codes should be unlinked. [5]
