Abstrakt: This overview presents group-contribution models for predicting properties of pure polymers, polymer/solvent and polymer/polymer mixtures. The state of art can be easily considered taking into account that polymer solutions and blends are complicated systems, with frequent occurrence of LLE in many forms (UCST, LCST, closed loop), significant effect of temperature and polymer molar mass in phase equilibrium, the free-volume effects, and other factors causing these difficulties. The choice of a suitable model depends on the actual problem and demands, especially on the following: type of mixture (solution or blend, binary or multicomponent), type of phase equilibrium (VLE, LLE, SLE), conditions (temperature, pressure, concentration), type of calculation (accuracy, speed, yes/no answer, or complete design). The performance of various models and their range of application will be discussed.
