In addition, Tg criteria determined by DSC and DMTA measurements show miscibility on a scale down to 50-100 A (7). For example. Figure 6 shows storage modulus vs. temperature curves for PVP and for the PPTA anion/PVP (2/98) molecular composite. For both, there is a single Tg, which is ca. 15 C higher for the composite than for PVP. DSC data also show only a single Tg up to 400 C, which increases with increasing the ionic PPTA content (see Figure 7).
