Abstract
Vapor-liquid equilibria have been measured for comb and linear polymer s using a gravimetric-sorption method in the temperature range 50-70 d egrees C. Polymers were poly(styrene-co-maleic anhydride) with alkyl s ide chains of different length (C5, C12, C22) and poly(styrene-co-male ic anhydride) and poly(maleic anhydride). Solvents were acetone, metha nol and cyclohexane. Due to different chemical structures, the phase b ehavior of the comb polymer solutions strongly depends on the ratio ba ckbone/side chains. Freed's lattice-cluster theory gives a good repres entation of the data. (C) 1997 Elsevier Science B.V.
