Abstract (en)
[origin: DE19812856A1] The invention relates to a method for producing styrene polymers containing water as only inflating agent by polymerising styrene in an aqueous suspension in the presence of between 0.1 and 15 weight % of a solid matter which is insoluble in water and styrene, for example carbon black or graphite.
