MACROMOLECULAR COMPOUNDS OBTAINED BY REACTIONS ONLY INVOLVING CARBON-TO-CARBON UNSATURATED BONDS (production of liquid hydrocarbon mixtures from lower carbon number hydrocarbons, e.g. by oligomerisation, C 10 G 50/00) [2]
Notes
(1)
In this subclass, boron or silicon are considered as metals. [2]
(2)
In this subclass, the following expression is used with the meaning indicated:
-
"aliphatic radical" means an acyclic or a non-aromatic carbocyclic carbon skeleton which is considered to be terminated by every bond to:
(a)
an element other than carbon;
(b)
a carbon atom having a double bond to one atom other than carbon;
(c)
an aromatic carbocyclic ring or a heterocyclic ring.
Examples: Polymers of
(a)
CH2=CHOCH2CH2NHCOOCH2CH2OH are classified in group C 08 F 16/28;
(b)
are classified in group C 08 F 16/36;
(c)
are classified in group C 08 F 12/18. [2]
(3)
In this subclass, in the absence of an indication to the contrary, a catalyst or a polymer is classified in the last appropriate place. [2]
(4)
In this subclass:
(a)
macromolecular compounds and their preparation are classified in the groups for the type of compound prepared. General processes for the preparation of macromolecular compounds according to more than one main group are classified in the groups for the processes employed (C 08 F 2/00 to
C 08 F 8/00). Processes for the preparation of macromolecular compounds are also classified in the groups for the types of reactions employed, if of interest; [2]
(b)
subject matter relating to both homopolymers and copolymers is classified in groups C 08 F 10/00 to C 08 F 38/00; [2]
in groups C 08 F 210/00 to C 08 F 238/00, in the absence of an indication to the contrary, a copolymer is classified according to the major monomeric component. [2]
(5)
In groups C 08 F 210/00 to
C 08 F 297/00, it is desirable to add the indexing codes relating to additional monomeric components, in cases where no specific subgroups defined by the said monomeric components are present. The indexing codes, which are chosen from groups C 08 F 210/00 to C 08 F 238/00, have the same numbers as the classification symbols, but a colon is used instead of the oblique stroke, and should be linked. [2]
(6)
Attention is drawn to Chapter IV of the Guide which sets forth the rules concerning the application and presentation of the different types of indexing code. [6]
