摘要
Solvent activity versus solvent weight fraction are reported for benzene, dichloromethane and n-propyl acetate in each of two different poly(methyl methacrylate) polystyrene copolymers and for dichloromethane and n-propyl acetate in polystyrene homopolymer. Results were obtained at 323.15 K for low solvent weight fractions using a quartz crystal balance. A modified Flory-Huggins equation is used to interpret the data.
