Active center (polymer science)

An active center (sometimes called active site or kinetic-chain carrier) in polymer science refers to the site on a chain carrier at which reaction occurs.[2]

IUPAC definition
The site on a chain carrier at which reaction occurs.

Note: In the Gold Book,[1] the terms “active center” and “active site”

are defined with reference to heterogeneous catalysis and the term

“reactive site” is used within the definition of chain polymerization.
