(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 ...
(2.5 mol-%) were prepared in chlorobenzene and polymerized. The yield of copolymer with a numerically average molar mass of 84,300 g/mol and a glass transition temperature of approx. 85° C. was 45% after 15 minutes. A molar copolymer composition of BCHAM:MMA=1.00:0.63 was determined by...
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 ...
Specifically, the pressure required to drive vesicles through narrow pores, p*, was found to decrease in the presence of EtOH from 0.233 MPa to 0.133 mPa; this is a decrease of approx. 40% and thus near the limit of insignificance (see Table 2 for comparison). The reason is the limited...
Absence of cycles from polymer demonstrated by GPC (oligomers in lower-molecular range) and MALDI-TOF (molar mass of the cycles in comparison with molar mass of the open-chain analogues) Example 2 Homopolyformal from Bisphenol A: 7 kg (30.66 mol) bisphenol A (Bayer AG), 3.066 kg (76.65...
3.The process as claimed in claim 1, wherein at least one of the alkali metal hydrogencarbonate or the ammonium hydrogencarbonate is present during the oxidizing in an amount of from 0.02 to 0.5 molar equivalent, based on the amount of the amine (I). ...
formed as the ratio of mass average to number average in the molar mass distribution, of at least 2. Preference is also given to a softening temperature of less than 20° C. The molar mass in this context is the weight average of the molar mass distribution, as is accessible, for exampl...
33. The rechargeable battery cell according to claim 1, wherein the molar concentration of the first conducting salt is in the range selected from the group consisting of from 0.01 mol/L to 10 mol/L, from 0.05 mol/L to 10 mol/L, from 0.1 mol/L to 6 mol/L and from 0.2 mol/L to...
ml) were added to 27.5 g of a mixture of syn- and anti-dimethylsilanediyl[2-methyl-4,8-di(3,5-dimethylphenyl)-1,5,6,7-tetrahydro-s-indacen-1-yl][2-methyl-4-(3,5-dimethylphenyl)-5-methoxy-6-t ert-butylinden-1-yl] zirconium dichloride (MCC) with an anti-/syn-ratio of approx...
Preferably, a slight excess of the lithium compound is used, quite particularly from approx. 4-10% compared with the theoretical value. A slight deficit of the lithium compound is less preferred, but the precise value also often depends on the reactivity of the TiO2starting product which can ...
