The association of living species in the anionic polymerization of e-caprolatone initiated by t-BuOLi in benzene solvent was studied by viscometry. It has been found that after complete conversion of e-caprolatone monomer
association of alkoxyl-lithium is indeed present and the association tendency increases with increasing initiator concentration. However
before monomer was consumed (i.e. during the course of propagation)
no intermolecular association between growing species was observed. The result is in good agreement withour kinetic study showing that the monomer lactone itself acts as a strong solvation agent.
