Abstract

Blends based on vinyl-aromatic polymers endowed with high tenacity and good chemical resistance, comprising: PA0 40 to 98% by weight of a vinyl-aromatic polymer containing from 0.5 to 5% by weight of a vinyl-aromatic monomer conjugated diene block copolymer; PA0 1-54% by weight of a polyolefine; and PA0 1-20% by weight of a vinyl-aromatic monomer-conjugated diene star block copolymer; the sum of the three components being equal to 100%.
