## 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~
