Polycondensates modified by chemical after-treatment

Introduced: July 1974

Full Title

Full titles differ between systems:

IPC:

Polycondensates containing more than one epoxy group per molecule; Macromolecules obtained by reaction of epoxy polycondensates with monofunctional low-molecular-weight compounds; Macromolecules obtained by polymerising compounds containing more than one epoxy group per molecule using curing agents or catalysts which react with the epoxy groups > Polycondensates modified by chemical after-treatment

CPC:

Polycondensates containing more than one epoxy group per molecule (low-molecular-weight polyepoxy compounds C07); Macromolecules obtained by polymerising compounds containing more than one epoxy group per molecule using curing agents or catalysts which react with the epoxy groups > Polycondensates modified by chemical after-treatment

CPC subdivides this area 3x more granularly than IPC with 3 additional codes.

3 codes are CPC-only extensions, 1 exist only in IPC.

IPC defines codes here since 1974.
