What is 2,5-Furandione, dihydro-, monopolyisobutylene derivs CAS 67762-77-0?

(PIBSA, CAS 67762-77-0) is a functional chemical synthesized by the reaction of highly active polyisobutylene (Mn=1000) and maleic anhydride. It has surface activity, dispersibility and thermal stability, and is a core intermediate for the preparation of ashless dispersants, emulsifiers and lubricant additives. The polar groups and non-polar segments in its molecular structure give the product a unique “amphiphilicity”.
