Living polymerization of methacrylic esters with aluminium porphyrin initiators. Axial ligand exchange activities of alkyl??and enolate??aluminium porphyrins in relation …
Abstract Polymerization of methacrylic esters such as benzyl methacrylate using as initiator an-equimolar mixture of methylaluminium 5, 10, 15, 20-tetraphenylporphine [(TPP) AlMe] and 2, 7, 12, 17-tetramethyl-3, 8, 13, 18-tetramethylporphine [(EtioP) AlMe] proceeded from both initiators, affording a unimodal polymer of narrow molecular weight distribution, although the reactivities of (TPP) AlMe and (EtioP) AlMe are very different from each other. ...
