C-13 NMR analysis of propene/1-butene block copolymers obtained by gas-phase polymerization with Ziegler-Natta catalysts allows the determination of the propagation mte constants for the homopolymerization of the two monomers. They are very similar for the Solvay type catalyst delta-TiCl3/AlMe3 and the supported catalyst TiCl4/MgCl2/Phthalate/AlMe3. The constant of propene polymerization is three times higher than that of 1-butene polymerization. The high value of the constant found for propene polymerization is in agreement with the literature value determined by the stopped flow polymerization method.

Abstract
C-13 NMR analysis of propene/1-butene block copolymers obtained by gas-phase polymerization with Ziegler-Natta catalysts allows the determination of the propagation mte constants for the homopolymerization of the two monomers. They are very similar for the Solvay type catalyst delta-TiCl3/AlMe3 and the supported catalyst TiCl4/MgCl2/Phthalate/AlMe3. The constant of propene polymerization is three times higher than that of 1-butene polymerization. The high value of the constant found for propene polymerization is in agreement with the literature value determined by the stopped flow polymerization method.File in questo prodotto:
