Abstract
The current status of the statistical thermodynamics of dilute solutions of chain polymers is reviewed, with particular attention to the interactions between single chain molecules and solvents and to the mutul interactions of two chains. With respect to the problems of one and two chains, the following topics are considered: the potential of mean force between chain segments and its dependence on the slevent; relationship between latice and continuum theories; comparison between machine calculations and analytical theories of chain dimensions; exact series and approximate or semi-empirical theories of the osmotic second virial coefficient, and comparison with the experimental data; effects of polydispersity; behavior in mixed solvents. Higher virial coefficients and phase separation are also briefly discussed. Der heutige Stand der statistischen Thermodynamik der verdünnten Hochpolymerlösungen wird betrachtet. Folgende Probleme werden diskutiert: das Potential der Durchschnittskraft zwischen Kettenelementen und seine Abhängigkeit von dem Lösungsmittel; die Beziehungen zwischen Gittermodell und Kontinuum-Modell; ein Vergleich zwischen Monte-Carlo-Rechnungen und analytischen Theorien der Dimensionen von Kettenmolekülen; verschieden Theorien des zweiten osmotischen Virialkoeffizienten; der Einfluß der Molekulagewichtsverteilung; das Verhalten in Mischungen von Lösungsmitteln; der dritte Virialkoeffizient und die Phasentrennung.Keywords
