This invention relates to a composition, comprising: an unsaturated functionalized monomer of from about 5 to about 30 carbon atoms, which is: (a) polymerized to form a functionalized polymer; (b) copolymerized with a comonomer to form a functionalized copolymer; or (c) reacted with an enophilic reagent to form a polyfunctionalized monomer. The polyfunctionalized monomer may be polymerized to form a polyfunctionalized polymer which may be further reacted with one or more additional reagents. The invention relates to lubricants, functional fluids, fuels, dispersants, detergents and polymeric resins.

the allylicrearrangement of an alkenyl group; the yield of allylically-unrearranged monosulphide is negligible. The rates of the Ph3P-disulphide reactions increase with increasing solvent polarity and decrease with increasing alkyl substitution at γ-carbon atoms of the alkenyl groups or the α-carbon atom of the alkyl groups. The Ph3-P-tetrasulphide reactions are believed to involve nucleophilic substitutions
This invention relates to malienated derivatives made from maleic anhydride, functionalized monomers, and one or more additional reagents, e.g., an oxygen-containing reagent (e.g., alcohol, polyol), a nitrogen-containing reagent (e.g., amine, polyamine, aminoalcohol), a metal and/or a metal compound. The invention relates to lubricants, functional fluids, fuels, dispersants, detergents and functional compositions (e.g., cleaning solutions, food compositions, etc.)
This invention relates to functionalized monomers which are reacted with an enophilic reagent (e.g., maleic anhydride) to form an enophilic reagent modified functionalized monomer. The enophilic reagent modified functionalized monomer may be further reacted with one or more additional reagents (e.g., oxygen-containing reagents, nitrogen-containing reagents, metals or metal compounds). The invention relates to base oils which may comprise functional base oils. The invention relates to lubricants, functional fluids, fuels, dispersants, detergents and functional compositions (e.g., cleaning solutions, food products, etc.).
