Disclosed are novel polyether compounds obtained by the reaction or polymerization of 3,4-epoxy-1-butene in the presence of an onium iodide compound such as an ammonium or phosphonium iodide, an organotin compound such as a trihydrocarbyltin iodide, and a nucleophilic initiator compound. The polyether compounds comprise n units of residue (1) and m units of residue (2), wherein the total value of n + m is 2 to 70, m (n + m) is greater than 0.75 and up to 0.98, and residues (1) and (2) have the structures (1) and (2).

Nouveaux composés de polyéther obtenus par mise en réaction ou par polymérisation de 3,4-époxy-1-butène en présence d'un composé d'iodure onium tel qu'un iodure d'ammonium ou de phosphonium, d'un composé organostannique tel qu'un iodure trihydrocarbylstannique, et d'un composé initiateur nucléophile. Les composés de polyéther comportent n motifs du reste (1) et m motifs du reste (2), la valeur totale de n + m étant comprise entre 2 et 70, m/(n + m) étant compris entre 0,75 et 0,98, et les restes (1) et (2) ayant les structures (1) et (2).
