Abstract

Ethylene-modified latexes were prepared by emulsion polymerization of styrene and n-butyl methacrylate using ethylene-acrylic acid (EAA), [M(n): 18,800, acid number: 140], as a polymeric emulsifier respectively. EAA containing 20% portion of acrylic acid could form aggregates like micelles and the solubilization ability of the aggregates were dependent on the electrolyte concentration above 100% degree of neutralization of EAA. The polystyrene (PS) latexes prepared using EAA showed small particle size and monodispersed particle size distribution in the presence of excess neutralizing agent or relatively high content of electrolyte. The EAA improved the barrier properties of ethylene-modified poly(n-butyl methacrylate) (PBMA) films.
