  • Volumetric Properties of Ethylbenzene with Ethyl Acrylate, Butyl Acrylate, MEthyl MethAcrylate, and Styrene at 298.15 K
    Physics and Chemistry of Liquids, 2020
    Co-Authors: Rene D Peralta, Ramiro Infante, Gladis Cortez, JosÉ L. Angulo, Jaime Wisniak
    Abstract:

    Densities of the binary systems of Ethylbenzene with Ethyl Acrylate, butyl Acrylate, mEthyl methAcrylate, and styrene have been measured as a function of the composition, at 298.15 K and atmospheric pressure, using an Anton Paar DMA 5000 oscillating U-tube densitometer. The calculated excess volumes were correlated with the Redlich-Kister equation and with a series of Legendre polynomials. The excess volumes are positive for the systems Ethylbenzene + (mEthyl methAcrylate, Ethyl Acrylate) and negative for the systems Ethylbenzene + (butyl Acrylate, styrene).

  • Density and Volumes of Mixing of the Ternary System Ethylbenzene + Styrene + Ethyl Acrylate and its Binaries at 298.15 K
    Journal of Solution Chemistry, 2007
    Co-Authors: Jaime Wisniak, Ramiro Infante, Gladis Cortez, Rene D Peralta, Lidia E. Sandoval, Luis E. Elizalde, Homero Soto
    Abstract:

    Densities of the ternary system, Ethylbenzene + styrene + Ethyl Acrylate, and its three binaries have been measured in the whole composition range at 298.15 K and atmospheric pressure using an Anton Paar DMA 5000 oscillating U-tube densimeter. The calculated excess molar volumes are positive for the binary system, Ethylbenzene + Ethyl Acrylate, and negative for the systems Ethylbenzene + styrene and styrene + Ethyl Acrylate. The corresponding data were correlated with the Redlich-Kister equation and with a series of Legendre polynomials. Several models were used to correlate the ternary behavior from the excess molar volume data of their constituent binaries and were found to fit the data equally well. The best fit was based on a direct approach, without information on the component binary systems.

  • rheological and thermal properties of narrow distribution poly Ethyl Acrylate s
    Macromolecules, 2006
    Co-Authors: Laura Andreozzi, Valter Castelvetro, M Faetti, Marco Giordano, Fabio Zulli
    Abstract:

    In the present work, we characterize the rheological behavior of 10 nearly monodisperse poly(Ethyl Acrylate) samples, whose molar mass ranges from 1200 to 150 000 g/mol. The poly(Ethyl Acrylate)s were obtained by means of a controlled/living radical polymerization technique. The time−temperature superposition principle works, and the T dependence of the horizontal shift factor aTr(T) is fairly well described by the Williams−Landel−Ferry law. Furthermore, the zero-shear viscosity dependence on the temperature, for all the investigated samples, has resulted to be well described by means of Vogel−Fulcher laws. The mass dependence of thermal parameters such as the Vogel temperature T0 and the pseudo-activation energy Tb has been worked out and compared to the mass dependence of the glass transition temperature Tg. This leads us to propose here a coherent way to describe their behavior and estimate several microscopic parameters in terms of free volume. Moreover, the molar mass dependence of material parameter...

  • Ceric(IV) ion-induced graft copolymerization of acrylamide and Ethyl Acrylate onto cellulose
    Polymer International, 2006
    Co-Authors: K. C. Gupta, Keerti Khandekar
    Abstract:

    Graft copolymerization of acrylamide (AAm) and Ethyl acryllate (EA) onto cellulose has been carried out from their binary mixtures using ceric ammonium nitrate (CAN) as an initiator in the presence of nitric acid at 25 ′ 1 °C. The extent of acrylamide grafting increased in the presence of the EA comonomer. The composition of the grafted chains (F A A m = 0.52) was found to be constant during the feed molarity variation from 7.5 x 10 - 2 to 60.0 x 10 - 2 mol L - 1 , whereas the composition of the grafted chains (F A A m ) was found to be dependent on feed composition (f A A m ). and reaction temperature. The effects of eerie (IV) ion concentration, reaction time and temperature on the grafting parameters have been studied. The grafting parameters showed an increasing trend up to 6.0 × 10 - 3 mol L - 1 concentration of CAN at a feed molarity of 30.0 x 10 - 2 mol L - 1 and showed a decreasing trend on further increasing the concentration of CAN (>6.0 x 10 - 3 mol L - 1 ) at a constant concentration of nitric acid (5.0 × 10 - 2 mol L - 1 ). The composition of the grafted chains (F A A m ) was determined by IR spectroscopy and nitrogen content and the data obtained then used to determine the reactivity ratios of the acrylamide (r 1 ) and Ethyl Acrylate (r 2 ) comonomers by using a Mayo and Lewis plot. The reactivity ratios of acrylamide and Ethyl Acrylate were found to be r 1 = 0.54 and r 2 = 1.10, respectively, and hence the sequence lengths of acrylamide (m M 1 ) and Ethyl Acrylate (m M 2 ) in the grafted chains are arranged in an alternating form, as the product of the reactivity ratios of acrylamide and Ethyl Acrylate (r 1 x r 2 ) is less than unity. The rate of graft copolymerization of the comonomers onto cellulose was found to be dependant on the 'squares' of the concentrations of the comonomers and on the 'square root' of the concentration of ceric ammonium nitrate. The energy of activation (ΔE a ) of graft copolymerzation was found to be 5.57 kJ mol - 1 within the temperature range from 15 to 50 °C. On the basis of the results, suitable reaction steps have been proposed for the graft copolymerzation of acrylamide and Ethyl Acrylate comonomers from their mixtures.

  • graft copolymerization of Ethyl Acrylate onto cellulose using ceric ammonium nitrate as initiator in aqueous medium
    Biomacromolecules, 2002
    Co-Authors: K. C. Gupta, Sujata Sahoo, Keerti Khandekar
    Abstract:

    Ceric ammonium nitrate (CAN) in the presence of nitric acid has been used as efficient initiator for graft copolymerization of the Ethyl Acrylate onto cellulose at 35.0 ± 0.1 °C. Graft copolymerization of Ethyl Acrylate onto cellulose has taken place through the radical initiation process. The graft yield and other grafting parameters have been evaluated by varying concentration of Ethyl Acrylate from 2.5 × 10-1 to 15.0 × 10-1 mol dm-3 and ceric ammonium nitrate from 5.0 × 10-3 to 25.0 × 10-3 mol dm-3 at constant concentration of the nitric acid (8.0 × 10-2 mol dm-3). The rate of graft copolymerization has shown 1.5 order with respect to the concentration of the ceric ammonium nitrate. The graft copolymerization data obtained at different temperatures were used to calculate the energy of activation, which has been found to be 28.9 kJ mol-1 within the temperature range from 20 to 50 °C. The effect of addition of cationic and anionic surfactants on graft copolymerization has also been studied. On the basis ...
