FIELD: polymer materials.
SUBSTANCE: expandable polystyrene granules are manufactured by polymerization of styrene (if needed, jointly with comonomers) in water suspension, whereto foaming agent is added before, during, or after polymerization. Method is characterized by that polymerization proceeds in presence of swollen graphite having average particle size 20 to 100 μm in amount 2 to 20 wt % as calculated for monomers and granulated expandable polystyrene.
EFFECT: achieved formation of halogen-free fire-protecting components.
