Abstract
The present invention discloses a polyether derivative and a preparation method therefor. The polyether derivative is: the polyether derivative of the present invention has a functional group introduced into the polyether chain, such that the derivative has an ether bond, an ester group, an amino group, a heteroatom, and other groups, enabling the derivative to have various functions such as anti-oxidation, anti-wear functionality, and anti-rust functionality, either without requiring additional additives or requiring fewer additional additives used to make up for the lack of base oil functions.
