Reactivity ratios for the terpolymerization of methyl methacrylate, vinyl acetate, and molecular oxygen

An Intimate Polycarbonate/Poly(methyl methacrylate)/ Poly(vinyl acetate) Ternary Blend via Coalescence from Their Common Inclusion Compound with -Cyclodextrin

In this study, we successfully report an intimate ternary blend system of polycarbonate (PC)/poly(methyl methacrylate) (PMMA)/poly(vinyl acetate) (PVAc) obtained by the simultaneous coalescence of the three guest polymers from their common -cyclodextrin ( -CD) inclusion compound (IC). The thermal transitions and the homogeneity of the coalesced ternary blend were studied by differential scannin...

Synthesis, Characterization, Molecular Docking and Cytotoxicity Studies of Bagasse Xylem Ferulate-Acrylamide/Methyl Methacrylate Composite

BXFL (bagasse xylem ferulate)-g-AM (acrylamide)/MAA (methyl methacrylate) was synthesized based on bagasse xylan(BX)-g-AM/MAA in 1-Butyl-3-methylimidazolium chloride ([Bmim] Cl) ion solution with Ferulic Acid (FL) as esterification agent. The various factors that were investigated influenced carboxylic acid ester substitution degree (DSC) of BXFL-g-AM/MAA. The structures of BXFL-...

prediction of optimum time for oxygen clearance in solution polymerization of vinyl acetate in isopropyl alcohol

as we know oxygen is one of the main inhibitors of polymerization of vinyl acetate. therefore, nitrogen is used in order to make sure of system's high purity. to maintain purity it is necessary to find out the rate of the oxygensolution in polymerization system under different conditions of polymerization. it is concluded that incoming nitrogen to the system would remove the oxygen from th...

Vinyl acetate formation by the reaction of ethylene with acetate species on oxygen-covered Pd(111).

The reaction pathway of vinyl acetate synthesis is scrutinized by reacting gas-phase ethylene (at an effective pressure of 1 x 10-4 Torr) with eta2-acetate species (with a coverage of 0.31 +/- 0.02 monolayer) on a Pd(111)-O(2x2) model catalyst surface in ultrahigh vacuum. It is found that the 1414 cm-1 infrared feature due to the symmetric OCO stretching mode of the acetate species decreases in...
