摘要：
Concerning fluorinated rubber (FPM), ionic liquids were incorporated in concentrations of 80 mmol, without any compatibility problems. Compared to the raw polymer, a significant lower glass transition temperature was observed for the FPM/IL-systems using DSC. Possible explanations are suggested for the opposite effect in the course of the T-g measurements regarding constant or increasing T-g despite adding IL to the polymer. NMR-relaxation measurements show increased chain mobility when IL is added to the FPM. With applied characterization methods a relationship between structure and properties of the composites should be identified.
