Abstract:
An additive for use in lubricants comprising a reaction product of:(A) a thiadiazole compound having formula (I): where Z is selected from the group consisting of a branched or straight chain C1 to C20 alkyl radical, a C1 to C20 thioalkyl radical, an alpha bound succinate half or full ester, wherein the ester alkyl is a C1 to C5 alkyl radical, an alkali metal, an alkyloxy linkage having formula (II): with R1 being selected from the group consisting of hydrogen, a C1 to C20 branched or straight chain alkyl radical, a phenyl radical, a C1 to C20 branched or straight chain alkyl-substituted-phenyl radical, and combinations thereof and R2 being selected from the group consisting of hydrogen, a C1 to C20 branched or straight chain alkyl radical, a phenyl radical, a C1 to C20 branched or straight chain alkyl-substituted-phenyl radical, and combinations thereof; and(B) a poly(ether)glycol having formula (III): where Q is selected from the group consisting of a hydroxyl radical, a branched or straight chain C1 to C20 alkoxy radical, a branched or straight chain C1 to C20 alkylcarboxyl radical, a mono-substituted, di-substituted, or tri-substituted glycerol residue, hydrogen, or combination thereof; where R3 and R5 are selected from the group consisting of hydrogen and a methyl radical, where R4 is selected from the group consisting of hydrogen, a branched or straight-chain a C1 to C20 alkyl radical, a phenyl radical, a C1 to C8 branched or straight chain alkyl-substituted-phenyl radical, a C1 to C20 branched or straight chain acyl radical, or combinations thereof; and where n is 1 to 300.
