Summary: | The present invention is related to expandable vinyl aromatic polymers comprising comminuted coke, said comminuted coke having an average stack height (Lc) of carbon crystallites less than 4 nm, a volume median particle diameter (D50) comprised between 0.8 and 4 μm and being characterized by a span (D90−D10)/D50 below 2.5. Molded parts produced from the expandable vinyl aromatic polymers prove low thermal conductivities for a low foam density. |
