BLENDS BASED ON VINYL-AROMATIC POLYMERS ENDOWED WITH IMPROVED CHARACTERISTICS OF CHEMICAL RESISTANCE

摘要

Blends based on vinyl-aromatic polymers endowed with improved characteristics of chemical resistance, comprising: from 10% to 90% by weight of an impactresistant styrenic copolymer containing from 8 to 30% by weight of an ethylenically unsaturated nitrile, from 15% to 45% by weight of an olefinic elastomer, and from 77% to 25% by weight of a vinyl-aromatic monomer, and from 90% to 10% by weight of a mixture of aromatic group containing resins constituted by from 70% to 99% by weight of an aromatic polycarbonate and from 30% to 1% by weight of an aromatic polyester. Such blends are particularly suitable to be heat-transformed into shaped bodies by extrusion in the automotive sector.
