摘要

Expandable vinyl aromatic polymers comprising: a matrix obtained by polymerizing 50-100% by weight of one or more vinyl aromatic monomers and 0-50% by weight of at least one co-polymerizable monomer; 1-10% by weight, calculated with respect to polymer (a), of an expanding agent embedded in the polymeric matrix; 0-25% by weight, calculated with respect to polymer (a), of a filler comprising carbon coke having an average diameter of between 0.5 and 100 m, with a surface area, measured according to ASTM D-3037/89, ranging from 5 to 200 m2/g; 0.05-10% by weight, calculated with respect to polymer (a), of expanded graphite in particle form, with a particle average diameter (size) ranging from 1 to 30 m, a surface area, measured according to ASTM D-3037/89, ranging from 5 to 500 m2/g and a density ranging from 1.5 to 5 g/cm3.
