The effect of a ligand structure on the catalytic activity of salophen chromium(iii) complexes in the ring-opening copolymerization of phthalic anhydride with a series of epoxides was studied.

Highly swellable glycidyl methacrylate terpolymers with styrene and a series of crosslinkers (divinyl benzene and ethylene, diethylene, and triethylene glycol dimethacrylates) were obtained by suspension polymerization. The loading capacities of the resins, their glass-transition temperatures, and their swelling characteristics in 20 solvents were examined with respect to the monomer composition. A selected resin was modified for a cobalt-imine complex and tested as a catalyst in a model ring-opening reaction.

2-Hydroxyethyl methacrylate copolymers with styrene and series of the cross-linkers (divinylbenzene and mono-, di-and triethylene glycol dimethacrylates) with low cross-linking degree (2-5 mol %) were obtained by suspension polymerization. Loading capacity of the resins, their glass transition temperature, and swelling characteristics in 20 solvents were analyzed depending on monomers composition.

Resins with amine functionalities were obtained as a result of chemical modification of low crosslinked terpolymers of glycidyl methacrylate with styrene and divinylbenzene or diethylene glycol dimethacrylate. The loading of amine groups, swelling in the selected organic solvents, and thermal properties of the resins were studied. FTIR, DSC, TGA, SEM, and stereomicroscopy methods were also applied for exploring of the resins.The amine functionalized resins were tested as sorbents for uptake of cobalt(II), copper(II), iron(III), and manganese(II) ions from methanol and its mixtures with methylene chloride. The study show that all polyamine functionalized resins uptake quickly Cu(II) ions from methanol solutions. Their ability to remove cobalt(II), iron(III), and manganese(II) ions from solution depended on the mutual compatibility of solvents and resins. It increases clearly when the mixtures of methanol and methylene chloride are applied. V C 2011 Wiley Periodicals, Inc.
