Titles differ between systems:

IPC: Homopolymers of cyclic compounds having no unsaturated aliphatic radicals in a side chain and having one or more carbon-to-carbon double bonds in a heterocyclic ring

CPC: Homopolymers of cyclic compounds having no unsaturated aliphatic radicals in a side chain and having one or more carbon-to-carbon double bonds in a heterocyclic ring (cyclic esters of polyfunctional acids C08F118/00; cyclic anhydrides or imides C08F122/00)

Full titles differ between systems:

IPC:

Homopolymers of cyclic compounds having no unsaturated aliphatic radicals in a side chain and having one or more carbon-to-carbon double bonds in a heterocyclic ring

CPC:

Homopolymers of cyclic compounds having no unsaturated aliphatic radicals in a side chain and having one or more carbon-to-carbon double bonds in a heterocyclic ring (cyclic esters of polyfunctional acids C08F118/00; cyclic anhydrides or imides C08F122/00)

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.

IPC defines codes here since 1974.
