DIFF Subclass Not Allocatable
C08F

MACROMOLECULAR COMPOUNDS OBTAINED BY REACTIONS ONLY INVOLVING CARBON-TO-CARBON UNSATURATED BONDS

Introduced: September 1968

Description

C08F covers macromolecular compounds (polymers) synthesized exclusively through reactions of carbon-to-carbon unsaturated bonds, including addition polymerization, ring-opening polymerization of unsaturated monomers, and related transformations. This encompasses synthetic polymers derived from alkenes, alkynes, dienes, and cyclic unsaturated compounds, as well as modifications of such polymers. The subclass excludes polycondensation and polyaddition reactions involving functional groups other than C=C or C≡C unsaturation, which are classified elsewhere in C08.

Of 88 combined children, 81 exist in both systems.

7 codes are CPC-only extensions.

Note: 7 CPC extensions are marked as secondary classification only.

50 shared codes have differing titles between IPC and CPC.
