Polyacrylamide (PAM) was prepared by a new method of inverse microemulsion polymerization, with (NH 4) 2 S 2 O 8 -Na 2 SO 3 as initiator and liquid paraffin/Span80-Op10/AM-H 2 O-NaAc as polymerization system in this paper.
SNF Emulsion Handbook E | PDF | Emulsion | Pump
This document provides an introduction and overview of polyacrylamide emulsions. It discusses that emulsions are dispersions of a hydrogel polymer in an oil phase, stabilized by surfactants. They differ from powders in being simpler to handle but more complex multicomponent products. The document outlines contents to guide users on proper storage, handling, production of polymer solutions from …
