(G1820-60410, Agilent). All measurements were carried out by monitoring the signal of the107Ag and197Au isotopes, in He mode using the ORS3collision cell. Data processing was performed within the Agilent Mass Hunter software. The 99.996% purity argon and 99.999% purity helium gases were ...
A good thermal stability is provided if the molecule has a high molar mass, contains a large number of atoms and has a higher Tg. This can be measured in that the ambient temperature for the transistor can be increased slowly, for example from room temperature to approx. 300° C., for ...
polycarbonates of known molar mass distribution (for example from PSS Polymer Standards Service GmbH, Germany). This was done by employing method 2301-0257502-09D (from 2009 in German) from Currenta GmbH & Co. OHG, Leverkusen. Dichloromethane was used as eluent. The column combination consisted ...
Factors which are crucially relevant for using the novel starches are, on the one hand, the structure, water content, protein content, lipid content, fiber content, ash/phosphate content, amylose/amylopectin ratio, molar mass distribution, degree of branching, granule size and shape, and crystallin...
As an alternative, the production of the spinning mass can also be performed via the direct dissolution of the pulp in NMMO, containing approx. 13% water (NMMO monohydrate) in e.g. an extruder. The addition of the flame-retardant agent can be performed in powder form or as a dispersion ...

which also contain small proportions (approx. 2%) of structural units of the type Conventional commercial polyvinyl alcohols, which are offered for sale as white-yellowish powders or granules with degrees of polymerization in the range from approx. 100 to 2500 (molar masses of approx. 4000 to 10...
In the case of electrolyte 1, a maximum conductivity can be seen at a concentration of compound 1 of 0.6 mol/L-0.7 mol/L with a value of approx. 37.9 mS/cm. In comparison, the organic electrolytes known from the prior art, such as, e.g., LP30 (1 M LiPF6/EC-DMC (1:1 by ...
over anhydrous sodium sulfate. The solvent was distilled off under vacuum and the crude product was purified by chromatography (flash silica gel with ethyl acetate/hexane: 1/3). 32.44 g (71% yield) of a colourless liquid was obtained as a mixture of diastereoisomers (ratio: approx. 9/1)....
