Influence of molar mass on the diffusion and solubility behaviour of methyl ethyl ketone-isopropyl alcohol mixtures in poly(methyl methacrylate)fractalsmall flocsprojectionflee simulationpolystyrene latexPoly(methyl methacrylate) PMMA is used extensively as an electron beam resist. The development of the ...
In order to normalize the polymer property with its molar mass the intrinsic viscosity is determined by extrapolation of reduced viscosity to zero mass concentration [6]. We may now establish an activity coefficient relative to the extreme value. Assume that disintegration of the stacked asphaltene ...

The reaction kinetics, mass transfer and solubility of carbon dioxide in a single or mixed aqueous solution of piperazine have been studied by various researchers [2], [3], [4], [5], [6], [7], [8], [9], [10]. Kadiwala et al. [8] concluded that piperazine had a capacity for...

“microdosing” studies to evaluate the pharmacokinetics of novel drug compounds22,23,24,25, extends the distance/time over which tracers can be transported to the imaging site26, and is critical in preclinical research, where much higher concentrations of the tracer per mass of the animal must...
Abstract: Method for producing polyacrylate adhesive compounds with a narrow molar mass distribution by radical polymerization and subsequent decolorization of colored reaction products resulting therefrom. Inventors: Prenzel, Alexander (Hamburg, DE)
Gas chromatography-mass spectrometry was employed for the analysis of furfural impurities. A comprehensive consistency analysis was performed for the obtained data. The experimental data were correlated with the NRTL, UNIQUAC and Wilson activity coefficient models. The results were compared with the ...
However, as documented by results represented in Figure 2, stobadine is the most potent compound either against the initiation reaction compared to its two derivatives during high-molar-mass hyaluronan oxidative degradation (cf. left panel in Figure 2) or against the chain-breaking propagation reacti...
