✦ Synopsis
A rapid and low cost method has been developed for the direct analysis of the residual monomer concentration of acrylamide from inverse-emulsion reactions. Inverse-emulsion polymerizations involve the dispersion of a water soluble monomer in aqueous solution in a continuous organic phase. The addition of a low-medium hydrophilic-lypophilic balance (HLB) steric stabilizer and continuous agitation is required to maintain emulsification. This method consists in inverting the "inverse" (water-in-oil) emulsion by utilizing a high * To whom correspondence should be addressed. acrylamide in the above products including gas + On leave from the Department of Chemistry, Comenius ~hromatography'-~ and high-performance liquid one HPLC procedure for the determination of residual acrylamide monomer involves breaking the emulsion through
