TL;DR: In this article, a vacuum electromicrobalance cell was used to measure the equilibrium data of nine binary solvent + polymer systems, including hexane, pentane, water, methanol, and ethanol.
Abstract: Vapor liquid equilibrium data of nine binary solvent + polymer systems were measured by a vacuum electromicrobalance cell. Solvents used were hexane, pentane, water, methanol, and ethanol. Polymers tested were poly(dimethylsiloxane), Mn, 26 000; poly(propylene oxide), Mn, 2000; poly(vinyl alcohol), Mn, 88 000; poly(acrylic acid), Mn, 1 250 000; and polycarbonate, Mn, 24 000. Measured equilibrium data were tabulated and discussed.

TL;DR: In this paper, a 2-(trimethylsilylmethyl)methyl)pyrazine expressed by formula II is reacted with 2-(tert.-butyldimethylsiloxy)benzaldehyde in a polar organic solvent such as tetrahydrofuran in the presence of an alkyl lithium such as n-BuLi dissolved in a hydrocarbon solvent, at a temperature from -78°C to ambient temperature to provide the compound expressed by I.
Abstract: NEW MATERIAL:2-[2-(2-Hydroxyphenyl)vinyl]pyrazine expressed by formula I. USE: The compound expressed by formula I is stable at ambient temperature and has good crystallinity, large second high frequency-generating (SHG) activity and excellent transparency, having λmax at 348nm of short wave region, useful as non-linear optical material and also as fluorescent brightener, larger dye, etc. PREPARATION: 2-(Trimethylsilylmethyl)pyrazine expressed by formula II is reacted with 2-(tert.-butyldimethylsiloxy)benzaldehyde expressed by formula III in a polar organic solvent such as tetrahydrofuran in the presence of an alkyl lithium such as n-BuLi dissolved in a hydrocarbon solvent such as n- hexane at a temperature from -78°C to ambient temperature to provide the compound expressed by formula I.
