This invention pertains to a novel thermal process for converting a fluoropolymer having cyano-functionalized perfluoroether pendant groups into a novel perfluoroalkyl-crosslinked fluoropolymer having perfluoroether pendant groups. The process comprises heating the fluoropolymer having cyano-functionalized perfluoroether pendant groups in the presence of Cl—F to a temperature in the range of 200 to 300° C. The fluoropolymer having cyano-functionalized perfluoroether pendant groups can first be formed into a shaped article, and the shaped article then subject to treatment in situ with Cl—F.
2. The polymer so formed is crosslinkable and useful for the preparation of shaped articles and photo-imaged coatings. The novel fluoropolymer can be thermally treated to form crosslinked fluoropolymers with highly stable perfluoroalkylene crosslinks. The novel fluoropolymer is conveniently prepared by treating a cyano-functionalized fluoropolymer with Cl—F.

This invention pertains to a novel perfluoroalkyl-crosslinked fluoropolymer with perfluoroether pendant groups. The perfluoroalkyl-crosslinked fluoropolymer hereof is particularly well-suited for use in chemically and thermally aggressive environments, in part by virtue of the highly stable perfluoroalkyl crosslink. The perfluroalkyl-crosslinked fluoropolymer hereof can be prepared by crosslinking in situ a crosslinkable precursor in the form of a shaped article. A crosslinkable precursor is a fluoropolymer having a dichloroamino-functionalized functionalized perfluoroether pendant group.
In an α-olefin manufacturing process by the oligomerization of ethylene using an iron complex of a diimine of a 2,6-diacylpyridine or a 2,6-pyridinecarboxaldehyde, in which certain substituted iminoaryl groups are present, less higher molecular weight unwanted products are produced when the diimine and/or its precursor arylamine does not have impurities with substitution on a second ortho position to the imino group. This leads to less fouling of the process apparatus and higher yields of desired α-olefins.
