Abstract: An acrylamide-based polymer which contains one or more multiquaternized (“multiquat”) monomer unit(s) is provided. The acrylamide-based polymer can be used in a papermaking process to reduce pitch and stickies deposition, improve retention and drainage, and enhance dry strength properties of paper. Also included is a method of controlling pitch and stickies deposition in papermaking comprising treating pulp slurry with an acrylamide-based polymer which contains one or more multiquaternized (“multiquat”) monomer unit(s).
