Abstract

Natural rubber latex diluted to 5 solids was rapidly and accurately sized using the Acousto-Sizer an instrument that makes use of electrokinetic effects to simultaneously determine particle size distribution (PSD) and zeta potential. The results obtained are consistent with the median size and degree of polydispersity observed by Transmission Electron Microscopy though the shape of the PSD obtained by the two methods shows some difference. The zeta potential of the latex found with the AcoustoSizer was consistent with that obtained by other methods. The measurement requires minimal sample preparation and indicates the possible application of electroacoustics to routine sizing in the processing of natural rubber latex.
