Chemical Modification of Polyisobutylene Succinimide Dispersants and Characterization of Their Associative Properties
Pirouz, Solmaz; Wang, Yulin; Chong, J. Michael; Duhamel, Jean (American Chemical Society, 2015-09-17)The secondary amines found in b-PIBSI dispersants prepared by attaching two polyisobutylene chains to a polyamine core via two succinimide moieties were reacted with ethylene carbonate (EC). The reaction generated urethane ... -
Synthesis and Characterization of Ethylene Carbonate Modified Polyisobutylene Succinimide Dispersants
Wang, Yulin (University of Waterloo, 2010-05-19)Succinimide-based dispersants are the most commonly used dispersants in the oil industry. They are used in engine oil to prevent the aggregation of carbon-rich particles generated during engine operation, and consequently ...
