ABSTRACT:
An oil-soluble additive for lubricating oil applications is provided by the formation of an adduct of thiocyanogen halide and polyalkene, removal of the hydrogen halide from said adduct and thermal rearrangement of the product to provide a polyalkenyl isothiocyanate which can be subsequently derivitized to provide a thiocarbamyl moiety containing product having excellent sludge dispersement properties.
