COMPOSITIONS OF MACROMOLECULAR COMPOUNDS( pesticides, herbicides A01N; pharmaceuticals, cosmetics A61K; explosives C06B; compositions based on polymerisable monomers C08F, C08G; paints, inks, varnishes, dyes, polishes, adhesives C09; lubricants C10M; detergents C11D; artificial filaments or fibres D01F; textile treating compositions D06 )
NOTE
-
Compositions classified in C08K according to note 3 of C08K, are not classified in C08L.

Documents classified before 09.2003: Classification is given in the form of C-Sets. The polymer in majority is given a C08L symbol, and the minor components are characterised by Indexing Codes taken from the list below. The Indexing Codes are linked. The polymer in majority is always first in the C-set. List of M08L codes: C08L 23/00 , C08L 23/26 , C08L 25/00 , C08L 27/00 , C08L 27/04 , C08L 27/12, C08L 29/00 , C08L 31/00 , C08L 33/00 , C08L 35/00 , C08L 37/00 , C08L 51/00 , C08L 53/00 , C08L 55/02 , C08L 61/04 , C08L 61/20 , C08L 63/00 , C08L 67/00 , C08L 67/02 , C08L 67/025, C08L 67/03 , C08L 67/04 , C08L 67/06 , C08L 67/07 , C08L 69/00 , M08L69/OOB, C08L 71/00, C08L 75/04 , C08L 77/00 , C08L 77/08 , C08L 77/12 , C08L 79/08 , C08L 79/085, C08L 81/00 , C08L 83/00 , C08L 85/00 , C08L 91/06 , C08L 95/00 or C08L 2666/00 - C08L 2666/86 . Documents from group C08L 23/00 - C08L 23/36 , C08L 45/00 - C08L 45/02 and C08L 49/00 have all been reclassified following Note 3 below. An additive is classified in the last appropriate place in the list as selected for each C08L group. Examples:
a. A composition based on a polyamide and a graft polymer is classified in ( C08L 77/00 , C08L 2666/24 ). b. A composition based on polyvinylchloride and containing CaCO3 is classified according to note 4 of CO8K, i.e. in ( C08K 3/26 , C08L 27/06 ). If this composition contains also a polyamide, then the classification will be ( C08L 27/06 , C08L 77/00 , C08K 3/26 ). c. A composition based on a polysiloxane ( C08L 83/04 ) and containing a second polysiloxane, a phenol and silica is classified in ( C08L 83/04 , C08L 83/04 , C08L 2666/34 , C08L 2666/58 ).

From 01.09.2003 until April 2012: Classification is given in the form of C-Sets. The polymer in majority is given a C08L class, and the minor components are characterised by Indexing Codes taken from M08L or M08K and they are linked or unlinked. The polymer in majority is always first in the C-Set. List of M08L codes in the C-Set: C08L 1/00 , C08L 81/00 , C08L 83/00 , C08L 91/06 , C08L 95/00 or C08L 2666/02 - C08L 2666/08 , C08L 2666/14 - C08L 2666/26 . Examples:
a. A blend of 60 parts polyvinylchloride ( C08L 27/06 ) and 40 parts polyamide is classified in ( C08L 27/06 , C08L 2666/20 ) and C08L 77/00 . b. A blend of 50 parts polyvinylchloride ( C08L 27/06 ) and 50 parts polyamide ( C08L 77/00 ) is classified in ( C08L 27/06 , C08L 2666/20 ) and C08L 77/00 , as well as in ( C08L 77/00 , C08L 2666/04 ) and C08L 27/06 . c. A composition based on polyvinylchloride and containing CaCO3 is classified according to [N: Note 4 of CO8K, i.e. in ( C08K 3/26 , C08L 27/06 ). If this composition contains also a polyamide, then the classification will be ( C08L 27/06 , C08L 2666/20 ) and C08K 3/26 . d. A composition based on a first polysiloxane ( C08L 83/04 ) and containing a second polysiloxane, a phenol and silica is classified in ( C08L 83/04 , C08L 83/04 , C08K 5/13 , C08K 3/36 ) and C08L 2205/02 .

From April 2012 onwards, after the notation C08L, notations concerning the other constituents of the composition may be added, in the form of C-Sets. The further constituent is added with an indexing code. The indexing codes are chosen from C08L 1/00 -C08L555/86 or C08K and they may be linked or unlinked: - C08L 1/00 - C08L 101/10 are linked. - C08L 2201/00 - C08L 2555/86 are unlinked. The polymer in majority is always first in the C-Set. Examples:
a. A blend of 60 parts polyvinylchloride ( C08L 27/06 ) and 40 parts polyamide ( C08L 77/00 ) is classified in ( C08L 27/06 , C08L 77/00 ). b. A blend of 50 parts polyvinylchloride ( C08L 27/06 ) and 50 parts polyamide ( C08L 77/00 ) is classified in ( C08L 27/06 , C08L 77/00 ) and ( C08L 77/00 , C08L 27/06 ). c. A composition based on polyvinylchloride and containing CaCO3 is classified according to [N: Note 4 of C08K, i.e. in ( C08K 3/26 , C08L 27/06 ). If this composition contains also a polyamide, then the classification will be ( C08L 27/06 , C08L 77/00 , C08K 3/26 ). d.

A composition containing a polyamide in majority, a polyester and a polyethylene is classified in ( C08L 77/00 , C08L 67/00 , C08L 23/06 ) and C08L 2205/03 .

WARNING
-
"Rubber" includes:
natural or conjugated diene rubbers;
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).
In this subclass:
compositions are classified according to the mutual proportions by weight of only the macromolecular constituents;
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.
