Latest Patents

Stachew's latest patents include innovative formulations aimed at enhancing the performance of lubricating oils. One of his notable inventions is a modified polyisobutylene succinimide dispersant that improves seal, sludge, and deposit performance. This composition is designed to reduce sludge and degradation of elastomer seals in engines. It comprises an oil of lubrication viscosity and a minor amount of a nitrogen-containing dispersant, which is a reaction product of a hydrocarbyl-substituted succinic acylating agent. This agent has a limited amount of low molecular weight substituent and is combined with a polyamine or condensed polyamine containing less than 20 mole percent of polyamine components of 6 or fewer nitrogen atoms.

Another significant patent involves an engine oil formulation that includes a dispersant and an aldehyde or epoxide for improved seal performance, sludge, and deposit performance. This lubricating composition consists of a major amount of an oil of lubrication viscosity and a minor amount of a nitrogen-containing dispersant with a total base number ranging from 20 to 160 on an oil-free basis. The improvement in this formulation is achieved by adding a sludge preventing and seal protecting additive.
