Characterization of phthalate internal donor in MgCl2 supported Ziegler-Natta catalyst by solid state 13C NMR
Ziegler-Natta catalyst for propylene polymerization, which TiCl4 and di-alkyl phthalate were supported on MgCl2, was analyzed by solid state 13C NMR. It was confirmed that the spin-lattice relaxation time (“relaxation time” hereafter) of carbonyl group in phthalate was shortened with increasing meas...
