This paper provides recommended terminology for chain polymerization, clarifying various categories and sub-categories based on mechanisms, activation methods, and reaction characteristics. It aims to create a standardized, understandable, and self-consistent language for the field, covering recent developments in this area.

The article acknowledges funding from IUPAC, but no other conflicts are explicitly stated. Given the nature of the paper as a terminological recommendation, direct financial conflicts seem less likely. However, some authors have affiliations with universities and research institutions, which could potentially involve indirect biases related to funding or research priorities within the field of polymer chemistry.

This paper provides valuable clarification and standardization of terminology in the field of chain polymerization. This will aid in communication and understanding within the scientific community. Therefore, despite not presenting original research findings, it is a significant contribution.
