    Abstract: Disclosed are novel saturated polyether compounds comprised of n units of residue (1) and m units of residue (2), wherein (i) residues (1) and (2) have the structures: ##STR1## (ii) the total value of n+m is 2 to 70 and m/(n+m) is 0.05 to 0.98; (ii) at least 98 percent of the terminal hydroxyl groups of the polyether have the structure: ##STR2## The polyethers are obtained by first polymerizing 3,4-epoxy-1-butene to produce unsaturated polyether precursors comprising residues (1A) and (2A) having the structures: ##STR3## and then hydrogenating the unsaturated polyether precursors. The hydrogenation advantageously is performed in the presence of a nickel hydrogenation catalyst.
