The definition of the term “conversion” is discussed for a variety of polymer syntheses. It is demonstrated that in contrast to organic and inorganic chemistry several different definitions are needed in polymer science. The influence of increasing conversion on structure and topology of homo‐ and copolymers is illustrated. Chain‐growth polymerizations, such as radical polymerization or living anionic polymerizations of vinyl monomers, condensative chain polymerization, two and three‐dimensional step‐growth polymerizations, ring–ring or chain–chain equilibration and chemical modification of polymers are considered.
