Abstract

^13^C NMR analysis of propene/1‐butene block copolymers obtained by gas‐phase polymerization with Ziegler‐Natta catalysts allows the determination of the propagation rate constants for the homopolymerization of the two monomers. They are very similar for the Solvay type catalyst δ‐TiCl~3~/AlMe~3~ and the supported catalyst TiCl~4~/MgCl~2~/phthalate/AlMe~3~. 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.
