Full titles differ between systems:

IPC:

Working-up of macromolecular substances to porous or cellular articles or materials; After-treatment thereof > by surface fusion and bonding of particles to form voids, e.g. sintering

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) > by surface fusion and bonding of particles to form voids, e.g. sintering (of expandable particles C08J9/232)

No child classifications to compare. This is a leaf node in both IPC and CPC.
