Thermogravimetric analysis vapor pressure

Son and coworkers also reported the syntheses of hyperbranched poly(carbosilanes) via hydrosilylation. In one report, they prepared a series of AB3 carbosilarylene monomers (5, 6 and 7)173 which polymerized cleanly and rapidly to form soluble hyperbranched polymers in high yields. The polymers, ranging in appearance from sticky solids to oils, were characterized by NMR spectroscopy, thermogravimetric analysis, differential scanning calorimetry and vapor pressure osmometry. The polymers possessed subambient Tg... 

Thermogravimetric analysis (TGA) and differential thermal analysis (DTA) were performed in air at a heating rate of lOK/min. on a PTC-lOA thermogravimetric analyzer. The adsorption isotherms for vapor-phase water and ethanol were measured using the BET method. The saturation pressures, Pq, of water and ethanol at 299K are 758 mmHg. Prior to the adsorption experiments, the samples were dehydrated at 673K in air for 4 h. 

The thermal stability as well as the vapor pressure of relatively volatile ILs can be measured by ambient pressure thermogravimetrical analysis with different gases...
