Abstract:

Provided are novel perfluoropolyether derivatives useful as lubricating oil or coating material which little cause decomposition and are therefore free from the problem of degradation in service. The perfluoropolyether derivatives are represented by the general formula (1): (1) wherein m is an integer of 3 to 200; p, q, r, and s are each independently an integer of 0 to 100; when p, q, r, and s are each independently an integer of 1 or above, the arrangement of -(CH₂CH₂O)- and -(CH₂CH(OH)CH₂O)- units is not particularly limited; and when one of r and p is an integer of 2 or above and the other is an integer of 1 or above or when one of q and s is an integer of 2 or above and the other is an integer of 1 or above, these units may be arranged in block or at random.
