Abstract:
1. A free radical polymerization process employing organometallic RAFT reagents, comprising: reacting at least one free radically polymerizable monomer, at least one initiator, and at least one organometallic RAFT reagent undergoing polymerization to obtain a polymer having terminal organometallic functional groups with a PDI of 1.4 or less, wherein the organometallic RAFT reagent has a formula (I), of or a formula (II), of: wherein n is 2, 3, 4, or 5; L is the same or different ligand which remains bound to M under polymerization conditions; T is the same or different and is P, C, O, or N; M is the same or different and is Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, Mn, Tc, Re, Fe, Ru, Os, Co, Rh, Ir, Ni, Pd, Pt or Sc; R R R
