Abstract

Polystyrene suspensions were synthesized by emulsion polymerization of styrene in the presence of a small additive (3% by weight) of polymethylmethacrylate (as stabilizer). The additive is not compatible with the formed polystyrene. Formed suspensions have narrow size distribution of the polymer granules with a diameter of 0.3-0.4 microns.


The kinetics of polymerization was studied by dilatometric method. The rate of reaction was determined. Dispersed composition of the polymer suspensions was studied by electrophoretic light scattering. Optimal conditions for obtaining the above mentioned polystyrene suspensions are: monomer/water phase ratio 1:25, initiator concentration 2%, the reaction temperature 70°C.


Obtained polystyrene suspension particles may be used as adsorbent-carriers of various bioligands (live cells, antibodies, viruses) for visualization during the rapid analysis and identification by optical microscopy.
