Abstract

Copolymers containing at least one perfluoropolyether segment and multiple aminooxalylamino groups are described. Methods of making the copolymers are also described. The copolymers can be prepared by reacting an oxalylamino-containing compound and an amine compound having at least two primary amino groups, at least two secondary amino groups, or at least one primary amino group plus at least one secondary amino group.
