Sorption of phenols on macroporous methacrylate copolymers containing ethyleneamine groups

Sorption and desorption of organic compounds by synthetic polymeric sorbents

“…Earlier, we investigated the sorption of substituted phenols by macroporous methacrylate copolymers (Hradil et al, 1986). This study was focused on the sorption of low-molecular-weight compounds (nitrobenzene, aniline, p-chloroaniline, and phenol) and larger molecules of nonionogenic surface active compounds-[oligo(ethyleneoxy)]benzenes (Triton X-100, X-305, and X-405).…”

“…The nonspecific interactions correspond to weak van der Waals forces and are related to the electron polarizability of the sórbate; the specific interactions involve dipole-dipole interactions, formation of hydrogen bonds, and the like and depend in the first place on dipole moments of the sórbate. If the specific interactions predominate over the nonspecific ones, the sorbed compound is dissolved in the polymer (Hradil et al, 1986).…”

Nanoporous microspheres: from controllable synthesis to healthcare applications

“…The hydrophobic monomeric droplets can be converted into polymer particles aer polymerization. Since the 1960s, Seidl 70 and Hradil 71 have synthesized nanoporous polymer microspheres by suspension polymerization. In the late 1970s, Ugelstad and co-workers proposed a two step seed swelling polymerization method by which polymer particles could absorb monomer molecules gradually from monomeric droplets and form a Fig.…”

Synthesis, structure, and properties of new methacrylic derivatives of naphthalene‐2,3‐diol

“…These materials are mainly copolymers of ethylene dimethacrylate. From time to time, applications of other methacrylate derivatives have been reported 3–5. Azanova and Hradil6 described the preparation and sorption properties of methacrylate and functionalized methacrylate macroporous copolymers.…”
