C08J 9/00 Working-up of macromolecular substances to porous or cellular articles or materials; After-treatment thereof (mechanical aspects of shaping of plastics or substances in a plastic state for the production of porous or cellular articles B29C)
Introduced: July 1974
Title
Titles differ between systems:
IPC: Working-up of macromolecular substances to porous or cellular articles or materials; After-treatment thereof
CPC: Working-up of macromolecular substances to porous or cellular articles or materials; After-treatment thereof (mechanical aspects of shaping of plastics or substances in a plastic state for the production of porous or cellular articles B29C)

Of 20 combined children, 13 exist in both systems.
7 codes are CPC-only extensions.
2 shared codes have differing titles between IPC and CPC.
IPC defines codes here since 1974.
