The Use of Flory-Huggins Parameters in Characterization of Polymer-Filler Compositions
Inverse gas chromatography (IGC) has been applied to observe the interactions in filled polymer/organic solvent as well as modified filler/polymer systems under conditions approaching infinite dilution of the volatile component. In our study we will show that the Flory-Huggins theory is useful in the characterization of the interaction in polymer-filler systems. Authors propose to express the magnitude of modified filler/polymer interactions by Flory–Huggins ' 23 χ parameter. We examined the series of compositions of polyethylene (M= 35000) with different amount of modified silica filler (5, 10, 20 % wt).
