Influence of reactive emulsifier on the stability and viscosity of acrylate emulsion

The acrylate emulsions have been synthesized using the reactive emulsifier allyloxy nonylphenol polyoxyethylene(10) ether sulfate(DNS-86).For comparison,the emulsions containing the conventional emulsifier sodium dodecyl sulfate(SDS) have been synthesized too.Effects of the emulsifiers on the emulsion stability and on the viscosity of the emulsion were discussed.The mechanism of the reactive emulsifier on the viscosity of emulsion was investigated.Compared to the conventional emulsifier SDS,the stability of the emulsions containing reactive emulsifier DNS-86 have been improved.When the amount of DNS-86 reached 2.0%,the stability of the emulsion was optimal.The viscosity of the emulsion increased with the increase of emulsifier content.The particle size of the emulsions containing the reactive emulsifier DNS-86 was larger and the distribution of particle size was narrower,and the viscosity of the emulsion was lower.
