MUMBAI, India, July 25 -- Intellectual Property India has published a patent application (202414058641 A) filed by Infineum International Limited, Abingdon, U.K., on Aug. 2, 2024, for 'amine containing polymers and lubricant compositions including such polymers and methods of using thereof.'
Inventor(s) include Haidasz, Evan; and Stol, Marianne.
The application for the patent was published on July 25, under issue no. 30/2025.
According to the abstract released by the Intellectual Property India: "Provided are functional polymers based on functionalized styrenic monomers including a nitrogen-containing moiety, other than as pendant to the phenyl ring that are polymerized from addition-polymerizable monomer compositions including amine-derivatized alpha-methyl styrene (ADAMS) monomers according to structure (I). wherein k is an integer from 1 to 3, preferably 2; wherein R1 is a methyl group or a phenyl group and R2 is a benzyl group, or wherein R1 and R2 are connected to form a moiety containing one 6-membered ring, with four carbons, bearing an O or N-CH3 group at the 4-position of the 6-membered ring; wherein R, in structure (I), is hydrogen, a phenyl ring co-attached at two neighboring ring carbon positions with the phenyl ring shown so as to form a naphthalene assembly, a phenyl group attached at a single carbon of the phenyl ring shown, a C1-C4 hydrocarbyl group (such as a methyl group), a C1-C6 hydrocarbyl group containing 1 to 4 additional heteroatoms (such as O, N, S, P, Se, and combinations thereof). Also provided are methods of using such functional polymers in lubricating oil compositions."
