Preparation method for nonionic polyacrylamide - Google Patents

A disclosed preparation method for nonionic polyacrylamide comprises the following steps: preparing an aqueous solution of acrylamide with a certain concentration, adding a sodium acrylate aqueous solution, mixing uniformly; adding an oxidant, a chain transferring agent and a reducing agent, mixing uniformly, initiating polymerization at 10 DEG C-15 DEG C; and after the polymerization is

polyacrylamide

Polyacrylamide

Polyacrylamide is a polyolefin. It can be viewed as polyethylene with amide substituents on alternating carbons. Unlike various nylons, polyacrylamide is not a polyamide because the amide groups are not in the polymer backbone. Owing to the presence of the amide (CONH 2) groups, alternating carbon atoms in the backbone are stereogenic

Polyacrylates

34.2.4 Nonionic polyacrylamides. Nonionic polyacrylamides represent the smallest group of acrylamide-based polymers, representing about 25% of the total polyacrylamide market. Nonionic polyacrylamide is somewhat misleading since in the manufacture of acrylamide, regardless of the route, some degree of hydrolysis of acrylamide occurs.

Rheology Properties of Underwater Cement Paste with Nonionic

Nonionic polyacrylamide was selected as anti-scouring admixture to eliminate the influence of different polymer electrical properties (Lu et al. 2022).The molecular weight of PAM is more than 10 million Daltons, and its main chain is connected with a C=O bond and an amino functional group as a branch chain structure, as shown in Fig. 2.

Polyacrylamide Soil Conditioners: The Impact on

Nonionic polyacrylamide has a strong hydrophilic character, greater than other nonionic, water-soluble polymers. Despite being described as nonionic synthetic polyacrylamides obtained as a result of polymerization or copolymerization of acrylamides, often contain in their macromolecules about 1¨C3% of anionic groups . These groups are formed
