A set of ω ‐bromoalkyl‐1‐glycidylethers were synthesized by reacting epichlorohydrin (ECH) and various ω ‐bromo‐1‐alkanols. The starting alcohols were readily obtained in good yields from the inexpensive 1, ω ‐alkanediols. The oxiranic monomers were polymerized using the Vandenberg chelate catalyst to give high molecular weight reactive polyether elastomers in very high conversions. Polymer NMR microstructural characterization showed their high degrees of regio‐ and stereoregularity. A comparative study with analogous polymers which had no glycidilyc oxygen showed that the new poly( ω ‐bromoalkyl‐1‐glycidylethers) had a higher degree of regioregularity. The thermal behavior and stability of these polyethers were also analyzed.
