ABSTRACT:
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: ##STR1##
