The situation of the general theory of plasticization is discussed. It is shown that the existing theories satisfactorily describe only particular cases, therefore exhibiting limited predicting capability. If the polymer and plasticizer compatibility is being evaluated unambiguously within the scope of the theory of polymer solutions then the plasticizer efficiency cannot be described unambiguously without allowance for the polymer system structure peculiarities. The necessity for studying "compatibility-efficiency-properties" taking into account the structure of the system considering that the structures in different concentration regions of the polymer-LML system can differ fundamentally is stressed. Plastifizierungsmechanismus und PolymerstrukturDer Stand einer allgemeinen Theorie der Plastifizierung wird diskutiert. Es wird gezeigt, da13 die existierenden Theorien nur Spezialfalle behiedigend beschreiben und deshalb nur mit Einschrankungen Voraussagen machen konnen. Auch wenn die Vertraglichkeit von Polymer und Weichmacher im Rahmen der Theorie der Polymerlosungen eindeutig bestimmhar ist, kann die Wirksamkeit des Weichmachers daraus nicht eindeutig abgeleitet werden, ohne die Besonderheiten der Struktur des Polymer-Weichmacher-Systems zu beriicksichtigen. Es wird darauf hingewiesen, da13 es bei der Untersuchung der Vertraglichkeit-Wirksamlieit-Eigenschaftsbeziehungen notwendig ist, die Struktur des Systems in die Betrachtungen einzubeziehen und zu beachten, daD sich die Strukturen in verschiedenen Konzentrationsbereichen grundlegend unterscheiden konnen.
