What are the main differences between anionic and cationic p …
Anionic and cationic polyacrylamide are two types of polyacrylamide polymers with different charge properties. Here are the main differences between them: 1. Charge properties: The key distinction lies in their charge characteristics. Anionic polyacrylamide has a negative charge due to the presence of anionic groups (such as carboxylate or sulfate groups), while cationic polyacrylamide has a …
