group-transfer polymerization

initialism: GTP

Chain polymerization in which a specific atom or group is intramolecularly transferred to remain associated with the active chain-end during the course of polymerization.
Notes:
  1. Group-transfer polymerization is most often a reversible-deactivation polymerization or a coordination addition polymerization.
  2. The term group-transfer polymerization is often specifically associated with polymerization of (meth)acrylates and acrylamides initiated by silyl ketene acetals such as 1-methoxy-2-methyl-1-(trimethylsiloxy)prop-1-ene (traditional name is methyl trimethylsilyl dimethylketene acetal) and catalysed by nucleophiles.
  3. Other forms of chain polymerization commonly referred to as group-transfer polymerizations include catalyst-transfer polymerization and rare-earth-mediated or lanthanide-mediated coordination polymerization.
