The Appryl PP process is a proprietary bulk-phase liquid polymerisation technology developed jointly by Elf Atochem (later TotalFinaElf / ATOFINA, now TotalEnergies/Arkema) and BP Chemicals (later BP Amoco). It is classified as a second-generation bulk polypropylene process, belonging to the same family as other liquid-phase CSTR-based technologies.
The technology was developed and operated exclusively by the Appryl joint venture. Following its dissolution into INEOS (via the 2024 TotalEnergies acquisition), the process know-how and intellectual property now reside within INEOS O&P.
