[ 1 ] - Kinetic Study of Graft Polymerization of Acrylic Acid and Ethyl Methacrylate onto Starch by Ceric Ammonium Nitrate
Graft polymerization of acrylic acid (AA) and ethyl methacrylate (EMA) onto starch (St) were carried out in aqueous solution using ceric ammonium nitrate (CAN) as redox system under N2 atmosphere. The effect of pH, reaction time, temperature, concentrations of CAN, St, and monomers on the graft yield was investigated. Monomer reactivity was in the following order: AA>EMA.<em...
[ 2 ] - The effect of temperature and water absorption on enzymatic degradation of starch / polyvinyl alcohol blend film by α-Amylase
Thermoplastic starch (TPS) materials present several advantages to the plastic industry andwhen blended with other materials they can exhibit improved mechanical and moisturesensitivity properties compared to pure TPS materials. Further investigations on TPS: PVAblends are of particular interest due to their excellent compatibility and improved properties suchas tensile strength, elongation, to...
[ 3 ] - Effect of some additives on degradation of poly (vinyl chloride- co- vinyl
The thermal decomposition of 86 % vinyl chloride 14 % vinyl acetate copolymer wasstudied by the conductometry technique in the presence of nitrogen. The kinetics of stability andthermal degradation of vinyl chloride- co- vinyl acetate (PVC- co- PVAc) copolymer withcopper, copper oxide and tricalcium dicitrate (st) were investigated at various temperatures (150-180 oC ) in solution. The rate coe...
[ 4 ] - Kinetic study of unsaturated ketones epoxidation with hydrogen peroxide through the inverse phase transfer catalysis and effect of ultrasonic waves in this epoxidation
Kinetic study of epoxidation of unsaturated ketone of mesityl oxide was studied by usingHydrogen peroxide in the presence of dodecyltrimethyl ammonium bromide (DTAB) as aninverse phase transfer catalyst. The reaction was carried out in the two-phase media of waterheptanewith 1:1 ratio in 25 °C. It was found that the order of reaction for mesityl oxide forketone concentration in the range of 0.0...
[ 5 ] - Mechanical, Rheological and Computational Study of PVP/PANI with Additives
Polyvinylpyrrolidone/polyaniline emeraldine salt (PVP/PANI) with additives (TiO2, ZnO, NaCl, and Na2SO4) was synthesized via oxidative in situ polymerization. Because of using PVP/PANI as a protective membrane layer and its applications in an electrical device, we investigated the mechanical and rheological properties of PVP/PANI and other composites in orde...
