“…Vinyl phenol was obtained by decarboxilation of p-hydroxicinamic acid [38] and polystyrene-vinyl phenol copolymers (PS-VPh) were synthetized by radical copolymerisation under nitrogen atmosphere at 608C, using aa 0 -azo-bis-isobutyronitrile (AIBN) as initiator. In a typical experiment, about 40 g of styrene were mixed with the appropriate amount of vinyl phenol in the presence of 0.3 g of AIBN and the polymerization was allowed to run 12 hours for formation of random copolymers.…”

The compatibility of poly(methyl methacrylate) (PMMA) with poly(styrene-co-vinyl phenol) (PS-VPh) with two different contents of vinyl phenol, 5.8 and 7.2%, in dilute tetrahydrofuran solutions has been investigated by size exclusion chromatography and fluorescence spectroscopy at 258C. The chromatographic technique permits the evaluation of the preferential solvation at different PMMA/PS-VPh ratios. Changes in the fluorescence properties of PSVPh, caused by its association with PMMA, were used to obtain the fraction of copolymer bound to PMMA at diverse PMMA compositions. Both techniques agree quantitatively in every system, indicating that the association increases when the PMMA concentration and the content of the vinyl phenol in the copolymer increase.

synopsisThe chelating polymer-bearing triazolylazophenol moiety as the functional group was synthesized, its metal adsorption properties for 6 divalent heavy metal ions; Co2+, Ni2+, Cuz+, Zn2+, Cd2+, and Pb2+ were investigated. The capacity of the polymer for Cu2+ achieved 8.7 m&/g in pH 5.3 solution. The polymer showed remarkable color changes from orange to red violet or blue violet with its chelations to the heavy metal ions. The metal adsorption rates of the polymer were rapid in performing complete capacity saturation of heavy metal ions in about 30 min. The capacities varied little the presence of alkali or alkaline earth metal ions in solutions. The perfect elimination of metals from the polymer-M2+ chelates were performed with mineral acid solutions. The metal ions; Cu2+ and Ni2+ in plating-process solutions were effectively removed by the chelating polymer, and the polymer can be practically used for the removal of these ions from waste water.

SUMMARY:The radical pearl-copolymerization of 4-acetoxystyrene in the presence of divinylbenzene yields cross-linked poly-4-acetoxystyrene which can be carefully hydrolized to ply-4-hydroxystyrene. Poly-4-hydroxyetyrene reacts with diazocompounds to chelate forming polymers with o,o'-disubstituted azo-groups. The synthesis of a chelating resin based on 0-(2-hydroxyphenylezo)benzoic acid is described.
