摘要
The infinite diluted activity coefficients of solvents in polyisopropyl methylacrylate was measured using inverse gas chromatography. The solvents used were benzene, toluene, ethyl benzene, methyl acetate, ethyl acetate, propyl acetate, butyl acetate, methanol, ethanol isopropyl alcohol, butyl alcohol, 1,2-dichloroethane, and chloroform. It was observed that the infinite diluted activity coefficient of alcohols are well above those of the other solvents investigated.
1 INTRODUCTI0NDue to its short experimental time,little sampleneeded,suitable for broad temperature range,inversegas chromatography(IGC)has been widely used tomeasure variety of properties of polymer systems,suchas the infinite diluted activity coefficients of solvent inpolymer,the glass transition temperature of polymerand the surface properties of polymer,etc.
