Polyacrylamide (PAM) and Soils - USDA
Two polyacrylamide (PAM) compounds in which the NH2 was substituted with OH at 2% (2J) and 21% (21J), rendering them negatively charged, were used. Additionally, a guar compound (4246) used in the study was negatively charged and had a lower molecular weight than PAM. The soil was used without pretreatment and also with

Use of hydrophilic polymeric stabilizer to improve strength
Anionic polyacrylamide (PAM) was used as soil conditioner in the research. PAM was prepared by free radical polymerization of acrylamide in benzene with azoisobutyronitrile as initiator at 70°C for 24 h in a nitrogen atmosphere. PAM in the form of white powder was dried in a vacuum oven at 50°C. The average molecular weight

Surficial Stabilization of Wildfire-Burnt Hillslopes Using
Typical application rate for soil stabilisation is 0.56kg/ha, diluted 0.060kg per 1000 litres of water. Anionic PAM, in pure form, shall have no more than 0.05% acrylic monomer by weight. To achieve this requirement, the application rate for PAM, in its pure form, on slopes and channels, shall not exceed 224kg/ha (Wisconsin DoT specification).
