摘要:
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.

摘要:
A fluorinated bis(acyl-containing compound and a fluorinated polyester formed from the fluorinated diacyl are described. More particularly, the fluorinated diacyl has an aromatic ring bonded to two acyl groups plus at least one third group that contains a perfluoroalkylsulfonamido group. The fluorinated polyesters formed from the fluorinated diacyl-containing compound can be used to provide a low energy surface with a relatively low refractive index compared to many other polyesters.

摘要:
A method for immobilizing an amino-containing material to a substrate is described. The method involves providing a tethering compound with two reactive groups: a substrate reactive group and a fluoroalkoxycarbonyl group. The method further involves preparing a substrate-attached tethering group by reacting the substrate reactive group of the tethering compound with a complementary functional group on the surface of a substrate. The substrate-attached tethering group has a fluoroalkoxycarbonyl group that can be reacted with an amino-containing material to form an immobilization group that connects the amino-containing material to the substrate.
