Polyvinyl alcohol (PVA) / starch (S) /Carboxy methyl cellulose (CMC) composite films were prepared from PVA, three different loading of CMC and soluble starch aqueous suspensions by casting method in the presence of plasticize containing glycerol. The effects of the CMC addition on the some physical properties of the resulted blend films were investigated.(More)
Polyvinyl alcohol (PVA) / starch (S) /Carboxy methyl cellulose (CMC) / Montmorillonite (MMT) bionanocomposite films were prepared from PVA, MMT, CMC and soluble starch aqueous suspensions by casting method in the presence of a plasticizer that contained glycerol. The kinetics of thermal degradation of PVA/S/CMC/MMT blends was investigated by(More)
The focuses of this study were to investigate the effect of sodium montmorillonite clay (MMT-Na) content on the physical properties and extent of enzymatic hydrolysis Polyvinyl Alcohol (PVA): Starch (S): Carboxymethyl Cellulose (CMC) nanocomposites using enzyme <alpha>-amylase. The results of this work have revealed that films with MMT-Na content at 5 wt%(More)
Cis-polybutadiene was functionalized using in–situ generated DMD as oxidant and tetra-nbutyl ammonium bromide as phase transfer catalyst (PTC). The epoxidation process was investigated by 1 HNMR spectroscopy. 1 HNMR spectrum analysis of products confirms the absence of ring opening side products in epoxidation reaction. Various factors such as reaction(More)
