The mixed SDS/NP-40 (anionic/nonionic) surfactants were used to examine the generality of Smith-Ewart theory which was originally proposed for emulsion polymerization systems containing anionic surfactants. Our results are consistent with Smith-Ewart theory only when the wt%o of NP-40 in the surfact

β¦ Synopsis
An elastomeric terpolymer of butyl acrylate, methyl methacrylate and methacrylamide was synthesized by emulsion polymerization using an anionic surfactant. The latex terpolymer particles where shown to have a negative charge and the solid terpolymer was negatively charged with respect to Ringer's solution. Caval rings prepared from the latex and properly post treated and cured remained patent after implantation in the inferior vena cava of dogs through a 2 week period, thus demonstrating significant thromboresistance.

The copolymerization of styrene with two polymerizable surfactants (surfmers) based on maleic acid (dodecyl sodium sulfopropyl maleate and tetradecyl sodium sulfopropyl maleate) was studied in batch emulsion polymerizations. The surfmer conversion was obtained by serum replacement with water and sub
