Polyacrylamide can be divided into three types: cationic, anionic, and non-ionic polyacrylamide. Cationic polyacrylamide is classified by its ionicity, which includes values such as 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, and 70. Anionic polyacrylamide is categorized by molecular weight, ranging from 6 million to 22 million. Non-ionic polyacrylamide is also a linear polymer with a molecular weight between 6 million and 12 million.
Can cationic polyacrylamide be expressed by molecular weight? What is its molecular weight, and can anionic polyacrylamide and non-ionic polyacrylamide be expressed by ionicity? What are the differences and connections between the ionicity of polyacrylamide and its molecular weight?
1.Cationic polyacrylamide also has a molecular weight, but the molecular weight of cationic polyacrylamide is 12 million.
2.Anionic polyacrylamide and non-ionic polyacrylamide cannot be expressed in terms of ionicity due to their molecular structures.
3.The ionicity of polyacrylamide indicates the positive charge density of polyacrylamide. The molecular weight of polyacrylamide represents the length of the molecular chain in the polyacrylamide molecule.
4.The molecular structure of cationic polyacrylamide is a network polymer, so when representing its model, it is mainly expressed according to its ionicity.
5.The molecular structure of anionic polyacrylamide is a linear polymer, so when representing its model, it is mainly expressed according to the length of its molecular weight.
6.The molecular structure of non-ionic polyacrylamide is a linear polymer, so when representing its model, it is mainly expressed according to the length of its molecular weight. The molecular weight length of non-ionic polyacrylamide can only reach 12 million units.
