Active center (polymer science)
# Active center (polymer science)

   The site on a chain carrier at which reaction occurs.
   Note: In the Gold Book, 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.

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.
