Abstract:
Disclosed are novel polyether compounds obtained by the reaction or polymerization of 3,4-epoxy-1-butene in the presence of an acidic catalyst 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, n/(n+m) is a value in the range of 0.70 to 0.95, and residues (1) and (2) have the structures: ##STR1##
