C08L COMPOSITIONS OF MACROMOLECULAR COMPOUNDS (compositions based on polymerisable monomers C08F, C08G; artificial filaments or fibres D01F; textile treating compositions D06)
Introduced: July 1974
Description
C08L covers polymeric compositions and blends based on macromolecular compounds, including plastics, rubbers, and resins combined with additives, fillers, or other polymers. This subclass encompasses formulated materials ready for processing or use, such as polymer alloys, filled plastics, plasticized polymers, and composite matrices. It excludes the synthesis of individual macromolecules (covered in C08C, C08F, etc.) and focuses instead on compositions combining multiple components to achieve desired physical or chemical properties. Applications span thermoplastics, elastomers, thermosets, adhesives, coatings, and technical polymeric materials tailored for industrial or consumer applications.

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. aliphatic radical aliphatic radicals means an acyclic or 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 of CH 2 =CH-O-CH 2 -CH 2 -NH-COO- CH 2 - CH 2 -OH are classified in group ; CH 2 =CH-CO-CH=CH 2 are classified in group ; CH 2 =CH-C 6 H 4 -Cl are classified in group . 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. copolymer copolymers usually denotes a polymer of 2 chemically distinct monomers, and sometimes denotes a terpolymer 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. homopolymers homopolymer polymers resulting from the polymerisation of a single monomer or polymer with a single type of repeating unit. repeat(ing) unit repeat unit repeating unit the unit in an addition polymer which is repeated throughout the molecule; for example in polyethylene the repeat unit is: –CH 2 -CH 2 - rubber rubbers a. natural or conjugated diene rubbers; b. rubber in general.
