| description | A novel perfluoropolyether derivative which is less likely to undergo decomposition, which is free from a problem of deterioration during its use, and which is useful as a lubricating oil or a coating agent, is provided. A compound represented by the following formula (1): HO-(CH2CH2O)r.(CH2CH(OH)CH2O)p-CH2CF2O(CF2CF2O)mCF2CH2O- -(CH2CH(OH)CH2O)q.(CH2CH2O)s-H wherein m represents an integer of from 3 to 200, and each of p, q, r and s which are independent of one another, represents an integer of from 0 to 100, provided that when each of p, q, r and s which are independent of one another, is an integer of at least 1, the arrangement of -(CH2CH2O)- and -(CH2CH(OH)CH2O)- units is not particularly limited, and when one of r and p is an integer of at least 2 and the other is an integer of at least 1, or when one of q and s is an integer of at least 2 and the other is an integer of at least 1, these units may be arranged in a block form or at random. |
