     JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract Mechanism of mesoparticles modification reactions are considered with the application of such notions as charges quantization, phase coherence, interference and annihilation. On the base of theoretical Mesoscopics ideas the formation of covalent bonds because of the interference of negative charges quants in modification reactions is discussed. The hypothesis about possibility of annihilation at the interaction of positive and negative charges quants in redox processes is presented. The magnetic metal carbon mesoscopic composites synthesis (for example, initial metal carbon Mesocomposites) is realized by mechanochemical method at the grinding of metal oxides microscopic particles with polyvinyl alcohol macromolecules. Then in the result the Copper or Nickel Carbon mesocomposites which have the following atomic magnetic moments: for Copper – 1,3 μB, for Nickel – 1,8 μB are obtained. The investigat...

       JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract Shape memory polymers (SMPs) are the new class of smart fascinating polymer materials with different potential applications. This research work aims to present systematic investigations of electrically actuated shape memory (EASM) properties at different electric voltage of epoxy polymer filled with 0.1 to 0.4 wt. % of Graphene (GO) to develop SMPs nanocomposites. EASM effect and surface morphology functional analysis of composites were observed after EASM characterization by Field Emission-Scanning Electron Microscopy (FE-SEM) and Fourier Transform Infrared Spectroscopy (FT-IR). 0.4 wt. % addition of GO showed highest shape recovery at 180 S, 140 S and 95 S for 40 V, 60 V and 80 V respectively. These results suggest that GO could be promising materials for electrically actuated shape memory applications. Keywords:  Graphene Oxide; Epoxy; Smart Polymer; Shape Memory; Polymer Nanocompo...

     JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract Cationic polymerization of p-methyl styrene by phenacyl triphenyl phosphonium, phenacyl triphenyl arsonium and p, p`-bis[(triphenylphosphonio) methyl benzophenone salts [1-3], and cation radical salt of p-substituted triphenylamine having different p-substilments was carried out photochemically and/or thermally. Cation radical amine salts were found to be more effective thermally in comparison to phosphonium or arsonium salts. The effects of initiator structure, counter ion, concentrations of salts and reaction conditions on the rate of polymerization in dichloromethane on the isolated polymer will be presented Figure 1-3. Keywords:  Phenacyl triphenylphosphonium salts; Phenacyl triphenylparsonium salts; tri p-substituted triphenyl amine salts; p-methyl styrene; photo polymarization; thermal polymarization Introduction Poly (p-methyl styrene), PMS has excellent potential for a broad range of...

   JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract Studies of the elution dynamics of adsorption have revealed a close correspondence between the analytical solutions to (i) a direct problem formulated using an equilibrium adsorption layer model and (ii) an inverse problem formulated using the method of moments. Keywords:  Elution Dynamics; Adsorption; Charcoal; chromatograph; Numerical Equations Introduction The effects of adsorption dynamics on the elution peak profile for an arbitrary adsorption isotherm were previously analyzed in [1] using numerical simulations based on a model that assumed a layer of equilibrium adsorption (LEA model) [2]. Assuming linear adsorption dynamics, [1] revealed that the elution curves simulated using the LEA model agreed well with experimental data obtained for a given integer unit of relative adsorbent bed length (n). The solution parameters to the inverse problem, formulated using the method of moments for intege...
