C08G MACROMOLECULAR COMPOUNDS OBTAINED OTHERWISE THAN BY REACTIONS ONLY INVOLVING UNSATURATED CARBON-TO-CARBON BONDS
Introduced: September 1968
Description
C08G covers macromolecular compounds synthesized through mechanisms other than simple addition polymerization of carbon-carbon double or triple bonds. This includes polymers formed via condensation reactions (polyesters, polyamides, polyurethanes), step-growth polymerization, ring-opening reactions, and cross-linking processes. The subclass encompasses a broad range of industrial polymers such as phenolic resins, epoxy resins, polyimides, silicones, and various thermoset and thermoplastic materials. Excluded are vinyl polymers and elastomers derived purely from unsaturated hydrocarbon monomers, which fall under C08F (macromolecular compounds from unsaturated bonds).

Glossary
Addition polymers addition polymer Polymers in which unsaturated monomer molecules join together to form a polymer in which the molecular formula of the repeat unit is identical (except for the double bond) with that of the monomer. Block polymers block polymer Polymers formed by polymerisation of monomers on to a macromolecule having groups capable of inducing the formation of new polymer chains bound at one or both ends of the starting macromolecule, or by polymerisation using successively different catalyst types or successively different monomer systems without deactivating the intermediate polymer. Condensation polymers condensation polymer Polymers in which water or some other simple molecule is eliminated from 2 or more monomer molecules as they combine to form the polymer or crosslinks between polymer chains. Copolymers copolymer Usually denotes polymers of 2 chemically distinct monomers, and sometimes denotes terpolymers containing more than 2 types of monomer unit. Graft polymers graft polymer Macromolecular compounds obtained by polymerising monomers on to preformed polymers or on to inorganic materials. Such preformed polymers could be rubbers, polysaccharides, condensation polymers, homopolymers or copolymers of the addition polymer type.
