ABSTRACT:
Triazole compounds are grafted onto alkyl or alkenyl succinimides by using diisocyanates to effect the coupling. The process is carried out by first reacting a 1,2,3 -triazole with a diisocyanate to produce a triazole substituted urea addition product containing a single unreacted isocyanato group. This intermediate reaction product is then reacted with an alkyl or alkenyl succinimide ashless dispersant prepared from an alkyl or alkenyl succinic acid or anhydride and a polyamine by known methods. The novel composition so produced comprises a multifunctional hydrocarbon fuel or lubricant additive.
