Miscibility of Non‐Uniform Aliphatic Polyamide Mixtures
Abstract: Mixing different aliphatic polyamides provides opportunities to tune and optimize the properties of these semicrystalline polycondensates. Combining experiment and theory, we predict and explain the miscibility of aliphatic polyamide mixtures. Visual inspection and Raman spectroscopy of polyamide mixtures show that liquid/liquid phase demixing occurs in the melt due to limited miscibility. The large number of potential polyamide mixtures makes it challenging to test all miscibilities experimentally. Moreover, the dependence of miscibility on dispersity and the presence of water implies further challenges to a systematic experimental approach. Our theory predicts polyamide miscibility, while accounting for amide content, non‐uniformity, and moisture content, using generalizations of Flory–Huggins theory. Predicted miscibilities align with experimental results obtained on tested mixed polyamides. The gained insights guide the optimization of functional polyamide blends.
