    Notes: Ionic diols with varying methylene spacers were prepared from maleic anhydride and linear diols. Reaction across the unsaturated site by aqueous sodium bisulphite was used to prepare the ionic diols. Chain extended polyurethane ionomers were prepared by the reaction of prepolymer based on different polyols and diisocyanates with the ionic diols. The polyurethane anionomers were characterized by FT-IR and FT-NMR spectroscopy. The differential scanning calorimetric results show that Tg of the anionomers shifted towards low values as the ionic content in the polyurethane increases and as the length of the ionic diol increases. © 1996 John Wiley & Sons, Inc.

    Synthesis of casein-G-poly(vinyl acetate). II (1983)
    New York : Wiley-Blackwell
    Journal of Polymer Science: Polymer Chemistry Edition 21 (1983), S. 3041-3053

    Notes: Poly(vinyl acetate) was graft-copolymerized onto casein in the presence of potassium peroxydisulfate-ascorbic acid. The effect of synthetic variables on the rates of conversion of monomer (Rp), graft copolymerization (Rg), and homopolymerization (Rh), percent grafting, and grafting efficiency were investigated and the results, compared with the system initiated by peroxydisulfate alone.

    Graft copolymerization of ethyl acrylate onto gelatin using hydrogen peroxide and ascorbic acid in aqueous medium (1985)
    New York : Wiley-Blackwell
    Journal of Polymer Science: Polymer Chemistry Edition 23 (1985), S. 2865-2874

    Notes: Gelatin a derived protein from collagen can be modified at 60°C by allowing it to react with ethyl acrylate by use of a novel initiator technique. The polymeric ethyl acrylate side chain is chemically bonded to gelatin. The effects of synthetic variable in the graft copolymerization reactions have been discussed in the light of percent grafting, grafting efficiency, and the rate of polymerization.
