ORGANIC MACROMOLECULAR COMPOUNDS; THEIR PREPARATION OR CHEMICAL WORKING-UP; COMPOSITIONS BASED THEREON

Description

Class C08 encompasses the chemistry of organic macromolecular compounds, including their synthesis, chemical modification, and material formulations. This class covers polymers (both natural and synthetic), elastomers, resins, and other high-molecular-weight organic substances, along with their chemical working-up and processing into compositions. It includes subclasses addressing polymer synthesis methods, chemical reactions performed on polymers, cross-linking, blending, and compounding of macromolecular materials for practical applications.

IPC and CPC are identically structured here. All 8 subcodes exist in both systems.

6 shared codes have differing titles between IPC and CPC.
