This paper is a short review of free-radical synthesis of polyacrylamide and copolymer with inverse emulsion polymerization. The developments on technology in recent year were summarized. The influence of synthesis, technological factors on the structure and properties of polyacrylamides was discussed. The kinetics, the mechanism of nucleation; the monomers latex stability, the bulk and shape of bakelites, the polyers form and molecular weight on inverse emulsion polymerization of acrylamide and copolymer were introduced in here.
