    Notes: Summary Crosslinked polystyrenes with pendant -CH2SOCH3 grouping are efficient phase-transfer catalysts in liquid-liquid reactions of 1-bromooctane with several inorganic nucleophiles. Direct introduction of -CH2SOCH3 grouping into polystyrene by the reaction of a halogenated polystyrene with methylsulfinyl-methylsodium is described.

    A metal sorbent with an unbound complexing agent: polyethylenimine-bead cellulose (1990)
    Springer
    Polymer bulletin 24 (1990), S. 533-538 
    Details
    ISSN: 1436-2449
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics , Physics
    Notes: Summary A sorbent was prepared with branched polyethylenimine fixed on bead cellulose without chemical reaction. The “jack-in-the-box” effect was used by means of which a part of the originally adsorbed PEI remains, after treatment with strong acid, almost irreversibly fixed to cellulose. The sorbent contains 1.4–3.0 mmol N/g of dry matter and is able to bind some double-charged cations from acid solutions, both from buffered media (pH 2–4) and from hydrochloric acid (1–4 M).

    Notes: Summary Oligo(N-acetyliminoethylenes), both free and grafted on polystyrene, polymethacrylate and cellulose were prepared by the ring-opening polymerization of 2-methyloxazoline. Their phase transfer catalytic activity in nucleophilic substitution reactions was examined.

    EDTA ester of bead cellulose a fast-kinetics chelating sorbent (1980)
    Springer

    Notes: Summary Crosslinked EDTA ester of cellulose (with 1–1.3 mmole bonded EDTA/g) was synthesized by the treatment of bead cellulose with EDTA bis-anhydride. Compared with the iminodiacetic acid resin, the cellulose EDTA ester exhibits a higher stability of Cu(II) chelates at low pH and a very high sorption rate of Cu(II). The sorbent is stable in neutral and acid medium, but is hydrolyzed by alkalies.

    Immobilized complexon amides-cation exchangers of high chelating activity (1983)
    Springer
    Polymer bulletin 9 (1983), S. 139-143

    Notes: Summary Several complexon cation exchangers with EDTA or DTPA complexon groupings attached through the amide bond to the polymer matrix of bead cellulose or of the methacrylate type were prepared. The cation exchangers are comparatively stable to alkaline hydrolysis. Chelating ability of the sorbents was examined by measuring the distribution coefficients in Cu(II) and Ni(II) sorption from EDTA solutions. In spite of the low total capacity cation exchangers with immobilized DTPA have distribution coefficients higher by an order of magnitude than a commercial iminodiacetic resin.

    Simple synthesis of polymeric primary aromatic amines (1988)
    Springer
    Polymer bulletin 19 (1988), S. 423-426

    ISSN: 1436-2449

    Topics: Chemistry and Pharmacology , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics , Physics
    Notes: Summary A new simple and versatile method of obtaining polymers bearing aromatic primary amino groups was developed. The method consists in the reaction of an alkylating polymer with sodium 4-acetylaminobenzenesulfinate and subsequent deacetylation of the intermediate polymer by acid hydrolysis. Alkylating polymers such as chloromethylated polystyrene resin, tosylated macroporous poly (2-hydroxyethyl methacrylate), macroporous poly(glycidyl methacrylate) and PVC were used in the alkylation performed either in an organic swelling solvent or in an aqueous suspension under phase transfer catalysis conditions. Yields in the alkylation step depend largely on the type of the alkylating group, hydrolysis yields are essentially quantitative.

    A polar macroporous sorbent for gas chromatography (1987)
    Springer
    Chromatographia 23 (1987), S. 286-288 
    Details
    ISSN: 1612-1112
    Keywords: Gas chromatography ; Macroporous copolymers of 2-hydroxyethyl ; methacrylate ; Graft polymers ; Polar sorbent for gas chromatography
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Summary The gas chromatographic behaviour of crosslinked macroporous 2-hydroxyethyl methacrylate grafted with 2-methyloxazoline was investigated and the range of applicability of the copolymer was assessed. Retention index values were measured on this copolymer and compared with those obtained on the terpolymer 2-hydroxyethyl methacrylate-ethylene dimethacrylate-acrylonitrile. Rohrschneider constants and efficiency data for selected sorbates are given. The use of this type of polymer in the separation of various types of compounds is documented by various examples.
