Blends based on vinyl-aromatic polymers having high tenacity and impact strength, comprising: a vinyl-aromatic copolymer containing from 2 to 25% by weight of an ethylenically unsaturated nitrile and a rubber amount not higher than 15% by weight; and a grafted polymer consisting of an elastomeric core having a transition temperature of the second order lower than 10 DEG C. containing, in the grafted form, chains of vinyl monomers. |
