ABSTRACT:
Adducts are formed in a process which involves the reaction of an olefin, including olefin polymers, with a dimeric thionophosphine sulfide. Further derivatives may be formed by reacting the resulting olefin-thionophosphine sulfide adduct products with amines, e.g., alkylene polyamines, aziridines, phosphines or metal salts, e.g., zinc salts. Or, alkylene polyamine- or aziridine- treated olefin-thionophosphine sulfide reaction products may be further reacted with metal salts, e.g., zinc acetate. A representative material can be prepared by reacting polyisobutylene with an arylthionophosphine sulfide, and then further reacting the resulting cyclic bis(phosphinodithioic acid) anhydride product with an alkylene polyamine or aziridine, which in turn, may be further modified by reaction with zinc acetate.
The oil soluble olefin-thionophosphine sulfide products, as well as its oil soluble derivatives outlined above, may be used as additives for lubricating oil, and petroleum fuels, e.g., gasoline or fuel oil.
