ORGANIC MACROMOLECULAR COMPOUNDS; THEIR PREPARATION OR CHEMICAL WORKING-UP; COMPOSITIONS BASED THEREON (production of artificial threads, fibres, bristles or ribbons Fulltext... Hierarchy... Expanded...D01)
MACROMOLECULAR COMPOUNDS OBTAINED BY REACTIONS ONLY INVOLVING CARBON-TO-CARBON UNSATURATED BONDS [2]
C08F
Note(s)
Inventions dealing with macromolecular compounds or their preparation are classified in the groups for the type of compound prepared. The processes of preparation should be secondarily classified in the groups for the types of reaction employed when such groups exist. General processes for the preparation of macromolecular compounds according to more than one main group are classified in the groups for the processes employed (Fulltext... Hierarchy... Expanded...Fulltext... Hierarchy... Expanded...C08F 2/00-C08F 8/00).
For the purpose of this sub-class, boron and silicon are considered as metals.
For the purpose of this sub-class, the term "aliphatic radical" means an acyclic or a non-aromatic carbocyclic carbon skeleton which is considered to be terminated by every bond to:
an element other than carbon
a carbon atom having a double bond to one atom other than carbon
an aromatic carbocyclic ring or a heterocyclic ring.
MACROMOLECULAR COMPOUNDS OBTAINED OTHERWISE THAN BY REACTIONS ONLY INVOLVING UNSATURATED CARBON-TO-CARBON BONDS [2]
C08G
Note(s)
In the absence of an indication to the contrary, an invention is classified in the last appropriate place within each main group. [2]
In this sub-class, group Fulltext... Hierarchy... Expanded...C08G 18/00 takes precedence. A second classification should be given if the polymers are obtained by reactions forming specific linkages for which an appropriate group is provided. [2]
An ingredient is always classified in the last appropriate place. [2]
Ammonium salts are classified in the same way as metal salts. [2]
In this sub-class it is desirable to add, in conformity with paragraph 61 of the Guide, after the double oblique stroke the symbols relating to complementary information concerning individual constituents of an invention unit which is already classified as such. This complementary information concerns the indication of additional compounding ingredients. [2]
In this sub-class, compositions are classified according to the mutual proportions by weight of only the macromolecular constituents. [2]
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]
In this sub-class it is desirable to add, in conformity with paragraph 61 of the Guide, after the double oblique stroke the symbols relating to complementary information concerning individual constituents of an invention unit which is already classified as such. This complementary information concerns the indication of the additional macromolecular constituents of the composition. [2]
The term "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). [2]
