Measurement of Infinite Diluted Activity Coefficient of Solvent in PBMA by Inverse Gas Chromatography Method

Inverse gas chromatography (IGC) method has been used to measure the infinite diluted activity coefficient of 16 solvents including aromatics, halogenated hydrocarbons, alcohols and esters in poly(butyl methacrylate)(PBMA) at temperatures from 343K to 433K.The molecular thermodynamic models of polymer solutions presented by Zhou et al. have been used to correlate the experimental infinite diluted activity coefficients of solvents in PBMA.
