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—(CH2CH2O)a.(CH2CH(OH)CH2O)b-Q- (X), CF3(CF2)sO(CF2CF2O)g— (Z), where a, b, s, g and Q are defined herein. The ratio (CF3/(OH+CF3)) of the total molar amount of CF3 groups in the groups represented by formula (Z) to the sum of the total molar amount of CF3 groups 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.
Claims14
An ether composition comprising at least two ether compounds (A) each of which has from 1 to 4 groups represented by the following formula (X) and from 0 to 3 groups represented by the following formula (Z), with the total of the groups represented by the formula (X) and the groups represented by the formula (Z) being 4:
- HO—(CH2CH2O)a.(CH2CH(OH)CH2O)b-Q- (X),
- CF3(CF2)sO(CF2CF2O)g— (Z),
- provided that in the above formulae (X) and (Z), a is an integer of from 0 to 100, b is 0 or 1, s is an integer of from 0 to 19, g is an integer of from 3 to 200, and Q is a polyfluorinated polymethylene group or a polyfluorinated polymethylene group having an etheric oxygen atom,
- wherein the ratio (CF3/(OH+CF3)) of the total molar amount of CF3 groups in the groups represented by the formula (Z) to the sum of the total molar amount of CF3 groups in the groups represented by the formula (Z) and the total molar amount of OH groups in the groups represented by the formula (X) is from 0.01 to 0.5.
