Molecules per macromolecule

Higashimura et al. Iwve studied the polymerisation of N-vinylcarbazole by iodine in chlorinated hydrocarbons. They found that the polymer DP s increased during the reactions and increased further after a second addition of monomer. This living behaviour was particularly evident at low temperature, since the DP s obtained were consistent with an initiation involving one iodine molecule per macromolecule formed, i.e. no transfer and no termination. This system looks very promising.
