ABSTRACT:
To provide an ether composition containing no —OCF2O— structure, having a low viscosity and being excellent in chemical stability in a wide temperature range. An ether composition comprising a polyether compound (A) containing at least two —(OCF2CF2)— units, containing no —OCF2O— structure and having an average molecular weight of higher than 2,000 and at most 20,000, and an ether compound (B) containing at least one —(OCF2CF2)— unit and having an average molecular weight of at most 2,000.
