The ‘immortal’ ring-opening polymerization (iROP) of pentadecalactone (PDL), catalysed by magnesium 2,6-di-tert-butyl-4-methylphenoxide (Mg(BHT)2(THF)2) is reported for the first time. The polymerization was shown to occur without the requirement for extensive drying techniques or inert atmosphere whilst retaining end-group fidelity. The iROP technique is also further demonstrated to be applicable to ε-caprolactone (εCL).
