Question

How to measure degree of hydrolysis in polyacrylamide?

Answer 1

Explanation:

The degree of hydrolysis gives a measure of the degradation of the polymer gel. The degree of hydrolysis is defined as the actual number of carboxylate (COO−) groups that could replace the amide group (CONH2) divided by the total number of amide and carboxylate groups [24,25].

❣️HERE IS YOUR ANSWER ~

:-) We can the measure degree of hydrolysis in polyacrylamide By the Abstraction method . A method of determining the degree of hydrolysis by potentiometric titration of polyacrylamide (PAA) with HCl and NaOH was developed. From the titration curves and the control of the degree of purity it is possible to calculate the level of hydrolysis and the quantity of pure acid contained in the PAA of a commercial product...
