    Abstract: Method of producing polystyrene particles, polystyrene particles obtained by such a method, and expandable polystyrene particles containing athermanous particles. In the method, styrene monomers are subjected to a polymerization reaction in the presence of athermanous particles to produce polystyrene particles. According to the invention, the athermanous particles comprise carbon particles having a conical shape, in particular at least 95 % of the carbon particles have the shape of cones, such as open cones, along with some disc-shaped particles. The particles are formed by overlapping carbon layers, with a largest dimension of less than micrometers. Excellent thermal insulation properties are exhibited for expanded products produced from the particles.
