Butyl methacrylate (BMA)-ethylene dimethacrylate (EDMA)-methacrylic acid (MAA) and BMA-EDMA-2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) monolithic columns were prepared by varying the percentage of ionic monomers for capillary electrochromatography. Monolithic columns with a higher content of ionic monomers provided better column efficiency, and the performance of BMA-EDMA-MAA monoliths...

Ionic liquid based systems are used to facilitate the cationic polymerization of isobutylene conventional grade polyisobutylene (PIB) using AlCl3 as an initiator. Specifically, compound 1-butyl-3-methylimidazolium chloride (IL) is employed a reference system due its simplicity, well polyionic (PIL), prepared via radical 1-butyl-3-vinylimidazolium chloride, and halloysite clay (Hal) supported io...
