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, C10G 50/00; fermentation or enzyme-using processes to synthesise a desired chemical compound or composition or to separate optical isomers from a racemic mixture C12P; graft polymerisation of monomers containing carbon-to-carbon unsaturated bonds on to fibres, threads, yarns, fabrics or fibrous goods made from such materials D06M 14/00)[2]

Note(s)
In this subclass, boron or silicon are considered as metals.[2,7]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: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. Examples: Polymers ofCH2 =CH—O—CH2-CH2 —NH—COO—CH2-CH2 —OH are classified in group C08F 16/28;[figure]are classified in group C08F 16/36;[figure]are classified in group C08F 12/18. Therapeutic activity of compounds is further classified in subclass A61P.In this subclass, the last place priority rule is applied, i.e. at each hierarchical level, in the absence of an indication to the contrary, a catalyst or a polymer is classified in the last appropriate place.In this subclass: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 groups C08F 2/00-C08F 8/00 for the processes employed. Processes for the preparation of macromolecular compounds are also classified in the groups for the types of reactions employed, if of interest;subject matter relating to both homopolymers and copolymers is classified in groups C08F 10/00-C08F 38/00;subject matter limited to homopolymers is classified only in groups C08F 110/00-C08F 138/00;subject matter limited to copolymers is classified only in groups C08F 210/00-C08F 246/00;in groups C08F 210/00-C08F 238/00, in the absence of an indication to the contrary, a copolymer is classified according to the major monomeric component. This subclass covers also compositions based on monomers which form macromolecular compounds classifiable in this subclass.In this subclass:if the monomers are defined, classification is made according to the polymer to be formed:in groups C08F 10/00-C08F 246/00 if no preformed polymer is present;in groups C08F 251/00-C08F 291/00 if a preformed polymer is present, considering the reaction to take place as a graft or cross-linking reaction; if the presence of compounding ingredients is of interest, classification is made in group C08F 2/44;if the compounding ingredients are of interest per se, classification is also made in subclass C08K.
