Notes:
Thermal stabilities of the crosslinked N-vinylcarbazole/poly(N-vinylcarbazole)-furfural polymers and of the phosphonic acid resins prepared thereform were studied by thermogravimetric analysis. The overall thermal stability of the crosslinked polymers is greater than the same for poly(N-vinylcarbazole) and is further improved upon phosphorylation. The resins are stable in 5N acids and water at 100°C. Isothermal oxidative degradation studies of the resins indicate significant increase in the capacities. pH metric titration of the resins shows the presence of mono and dibasic phosphonic acid groups. The resins realize about 90% of their capacities within 2 min of equilibration.
