“…The first weight loss at 20-110°C is related to moisture removal, the second weight loss at 250-300°C may be due to the loss of the carboxylic group and a third weight loss at 320-370°C can be attributed to thermal degradation of sulfonic acid groups. It was previously reported that sulfonate groups are thermally more resistant than carboxyl groups [11]. As was expected, the increase in sulfonated monomer content caused a thermo-stability enhancement.…”

“…5, confirmed that more ASTCA content increased the Tg and decreased the peak area under the matrix peak [10,11]. These results show a greater chain movement of ASTCAH 10 due to weaker intermolecular or intramolecular interaction than in ASTCAH 30.…”

“…Rheological measurements of the water‐swollen gels (0.10 g sample in 2.3 mL distilled water) were performed using a Paar‐Physica Osillatory Rheometer (MCR300, Germany) at 25 °C with parallel plate geometry (plate diameter 25 mm, gap 3 mm). The detailed procedure can be found elsewhere …”

“…For P(NIPAM-SPA) particles, new bands appear at 1410 and 1098 cm −1 that can be attributed to stretching of SO 3 − from the newly introduced SPA. 22 Thermogravimetric analysis (TGA) allows a comparison of temperature profiles and the residual mass of different particles. The relative mass as a function of temperature for M-PVA, M-PNIPAM 17 kDa, and M-P(NIPAM-SPA) particles is shown in Figure 2 (right).…”
