Oligo/polysuccinimides, process for producing thereof and their use

摘要

The invention is directed to oligo/polysuccinimides prepared from alkyl or alkenyl succinic anhydride, containing two or more imide groups, a method for producing such oligo-polysuccinimides, and the use thereof as dispersing agents in lubricant products, plasticizers in plastics, surface sizes for paper industry, reactive additives, for coating and composite applications, as well as encapsulating agents in pharmaceutical and speciality chemical products. In the method, a linear or branched C₄-C₂₄ alkyl or alkenyl succinic anhydride is reacted with an oligoamine having two or more primary amino groups to obtain the corresponding oligo/polysuccinimide.
