Vapor-liquid equilibria (VLE) have been obtained for solutions of hyperbranched polymers in chloroform, acetone, cyclohexane, methanol, acetonitrile or n-propylamine in the range 35 to 80{degrees}C. Polymers with different branched structures were studied: star, comb and dendritic polymers. Data interpretation is based on the lattice cluster theory (LCT) of Freed and coworkers. Unlike the Flory-Huggins theory, LCT can predict the effect of molecular architecture on thermodynamic solution properties.
