    Description / Table of Contents: Es wird auf Grund der Theorie über die Durchflußgeschwindigkeit für viskose Flüssigkeiten ein Ausdruck für Φ (die FLORYkonstante) gegeben, wonach Φ von dem Lösungsmittel und demgelösten Polymeren sowie von der Temperatur abhängen soll. Die Variation von Phi;, [η] und k, wobei die beiden letzten fundamentale Größen in der Gleichung c/ηsp = l/η - kc sind, wurde zur Bestimmung der ungestörten Dimension der polymeren Moleküle in Lösung benutzt. Die Bedeutung von k und von entsprechenden Ausdrücken wird erörtert. Die Werte von \documentclass{article}\pagestyle{empty}\begin{document}$\[ \left( {{{\overline {\text{r}_\text{0}^\text{2} } } \mathord{\left/ {\vphantom {{\overline {\text{r}_\text{0}^\text{2} } } \text{M}}} \right. \kern-\nulldelimiterspace} \text{M}}} \right)^{1/2} $\end{document} stimmen gut mit denen der Literature überein.
    Notes: Based on the theory of rate process for viscous flow, an expression for Φ (FLORY constant) has been given according to which Φ should depend on the polymer-solvent pair and temprature. The variation of Φ, [η], and k, the latter two being fundamental terms of the equation c/ηsp = l/η - kc, has been utilised for the determination of unperturbed dimension of polymer molecules in solution. The importance of k and the alternative expressions for the same are discussd. The values of \documentclass{article}\pagestyle{empty}\begin{document}$\[ \left( {{{\overline {\text{r}_\text{0}^\text{2} } } \mathord{\left/ {\vphantom {{\overline {\text{r}_\text{0}^\text{2} } } \text{M}}} \right. \kern-\nulldelimiterspace} \text{M}}} \right)^{1/2} $\end{document} are found to be in good agreement with the literature values.
