, A preliminary set of experiments on the ROP of BPL OBn mediated by BEMP in solution in an NMR tube (C 6 D 6, mol L ?1 ) showed that the polymerization remained ineffective over 4 h at 60°C (Conv. BPLOBn < 5%), as monitored by 1 H NMR spectroscopy

Z. Jedli?ski, P. Kurcok, M. Kowalczuk, and J. Kasperczyk, Note that the MALDI-ToF mass spectra previously recorded for PHB and PMLA Bn samples prepared form the alike BEMP mediated ROP of BL and MLA Bn , respectively, could not evidence, the possible presence of ?COOH end-capping group because the matrix/cationizing agent used did not enable it. 22 A revised analysis of these MALDI-ToF mass spectra is presented in the ESI (ESI, Fig. S14 and S15 ?) and shows that the ROP of BL and MLA Bn mediated by BEMP proceeds in the same way as the ROP of rac-BPL OR s, Die Makromolekulare Chemie, vol.28, pp.1651-1656, 1986.
