Abstract:
The present invention relates to a concentrated polymeric composition which comprises: a) vinyl aromatic polymers and/or copolymers in an amount ranging from 10% to 90% by weight, calculated with respect to the overall composition, with respect to the overall composition, b) at least one compound containing epoxy functional groups in an amount ranging from 0.01% to 5% by weight, calculated with respect to the overall composition, with respect to the overall composition, c) at least one infrared absorbing agent, in an amount ranging from 10% to 90% by weight, calculated with respect to the overall composition, with respect to the overall composition.
