FUSED-RING POLYCYCLIC AMINE FUNCTIONALIZED OLEFINIC POLYMERS FOR LUBRICATING OIL COMPOSITIONS

This disclosure relates to functionalized olefinic polymers comprising an olefinic polymer bound to at least one fused-ring polycyclic amine for each polymer molecule, wherein the fused-ring polycyclic amine comprises at least one secondary amine and at least one other heteroatom therein and further comprises at least one primary amine directly pendant thereto, wherein the at least one fused-ring polycyclic amine is bound to the olefinic polymer through the at least the one primary amine.

MEDIA LUBRICANTS SYNTHESIS WITH CLICK CHEMISTRY

A lubricant for magnetic media is synthesized using click chemistry. In one aspect the lubricant is according to general formula (I):

##STR00001##

where Rc is a fluorinated or non-fluorinated divalent linking segment; where each Re.sup.1 and Re.sup.2 is a click linker moiety that can be triazole or sulfone; n is from 2 to 50; where each Rb.sup.1 and Rb.sup.2 is an optionally non-fluorinated divalent linking segment optionally comprising at least one least one first anchoring functional group engageable with a protective overcoat of a magnetic recording medium; and where each of Rv.sup.1 and Rv.sup.2, when present, independently comprises a moiety having at least one second anchoring functional group engageable with the protective overcoat of the magnetic recording medium. The click linker moiety may also functional as an anchoring functional group.
