Synthesis Report on Understanding Side‑Chain Fluorinated Polymers and Their Life Cycle

This report provides an overview of existing scientific and technical information on side-chain fluorinated polymers (SCFPs), focusing on their identities and life cycle, and with a particular goal to map the existing landscape and highlight critical knowledge and data gaps. It focuses on the life cycle of SCFPs, including production and use, presence of other PFASs in the commercial formulations, degradation of SCFPs during use and end-of-life treatment, and environmental releases of SCFPs and other PFASs present in the commercial formulations. The report comes with a separate Annex comprising five spreadsheets providing information on: substances identities, use information, PFASimpurity studies, degradation studies and SCFP release.
