Abstract
Provided is an ether composition containing at least two ether compounds each of which has from 1 to 4 groups represented by formula (X) and from 0 to 3 groups represented by formula (Z), where the total number of groups represented by formula (X) and (Z) is 4:HO—(CHCHO).(CHCH(OH)CHO)-Q-  (X),CF(CF)O(CFCFO)—  (Z),where a, b, s, g and Q are defined herein. The ratio (CF/(OH+CF)) of the total molar amount of CFgroups in the groups represented by formula (Z) to the sum of the total molar amount of CFgroups in the groups represented by formula (Z) and the total molar amount of OH groups in the groups represented by formula (X) is from 0.01 to 0.5.
