Liquid chromatography of benzene derivatives on a porous methacrylate copolymer containing epoxy groups

Linear Solvation Energy Relationships To Explain Interactions Responsible for Solute Adsorption onto a Polar Polymeric Sorbent

“…The correlation in Figure suggests that dipolar or inductive mechanisms are responsible for the adsorption of monosubstituted benzenes or heterocyclics that have a single polar region but lack HBD acidity. Similar conclusions have been reported by Ageev et al . and Belyakova et al., who performed chromatographic studies with a polar copolymeric sorbent, a hexane eluent, and a series of monosubstituted, non-HBD benzene derivatives.…”

Monodisperse Hydrolyzed Poly(glycidyl methacrylate-co-ethylene dimethacrylate) Beads as a Stationary Phase for Normal-Phase HPLC

“…However, changes in swelling of the polymeric beads does not occur since the original back pressure is obtained immediately during the equilibration process while any deswelling would be much slower. The absence of changes in bed volume for different solvents has already been noted for the hydrolyzed poly(glycidyl methacrylate- co -ethylene dimethacrylate) beads in other chromatographic applications …”

“…The absence of changes in bed volume for different solvents has already been noted for the hydrolyzed poly(glycidyl methacrylateco-ethylene dimethacrylate) beads in other chromatographic applications. 16 Column Stability. Many different samples, some of them very complex, and various eluents were injected in the columns packed with poly(2,3-dihydroxypropyl methacrylate-co-ethylene dimethacrylate) beads during this study.…”

“…13,14 Glycidyl methacrylate beads prepared by the conventional suspension polymerization process were developed by Svec et al more than two decades ago 15 and used in numerous applications including liquid chromatography. 16 Recently, we developed a method for the preparation of monodisperse porous beads that allows fine control of both particle size and porous properties. This process can also be used for the preparation of porous beads from glycidyl methacrylate and ethylene dimethacrylate.…”
