Thermogravimetric analysis

1 A base titration procedure measures the equivalents of sulfonic acid in the polymer, and uses the measurement to calculate the acid capacity or equivalent weight of the pure polymer.

2 Thermogravimetric Analysis  was performed to test the decomposition temperature. The polymer were placed inside a furnace and heated from room temperature to 600°C at a heating rate of 10°C/min.
