Water Soluble Polymer Flocculants: Synthesis

For nonionic linear polymers, the average radius of gyration is estimated to be 0.06 M 1/2 nm (M is the polymer molecular weight). 7, 14 Therefore, the size of polymer molecules in solution for a polymer with molecular weight of 2 ¡Á 10 6 is approximately 85 nm, much greater than twice the double layer thickness in this example, and therefore

ANIONIC POLYACRYLAMIDE - Santos

Anionic polyacrylamide is the copolymer of acrylamide and acrylic acid. No studies on the environmental fate of polyacrylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biodegrade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concern to aquatic organisms.

The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers [80]. Both

Comparison of adsorption ability of PAM, APAM and CPAM on

Regarding the type of polymer charge, polyacrylamide can be divided into three types: nonionic (PAM), anionic (APAM), and cationic (CPAM). And can be use in water based drilling fluid (WBDF) to: (1) control fluid loss indices and rheological parameters of low clay content drilling muds; (2) promote the inhibition of clay swelling while drilling

2.1. Anionic PAM Anionic PAM was a kind of water-soluble polymer which was prepared by anionic monomer and acrylamide monomer, or obtained by hydrolysis of PAM. There were both amide group and anion group with negative charge on the long chain of the polymer, such as maleic anhydride, acrylic acid and its sodium salt.
