Polyacrylamide in Agriculture and Environmental Land
The word polyacrylamide and the acronym “PAM” are generic chemistry terms, referring to a broad class of compounds.There are hundreds of specific PAM formulations. They vary in polymer chain length and number and kinds of functional group substitutions as well as molecular conformation, the most important conformation variation being linear or cross‐linked conformation.
