Abstract
Polycarbonate composition exhibiting improved resistance to organic solvents comprised of, in admixture: PA0 (i) at least one high molecular weight thermoplastic aromatic polycarbonate resin; PA0 (ii) at least one selectively hydrogenated linear, sequential or radial teleblock copolymer resin of a vinyl aromatic compound (A).sub.n and (A').sub.n and an olefinic elastomer (B), of the A--B--A', A--(B--A--B).sub.n, A(BA).sub.n B, (A).sub.4 B, B(A).sub.4 or B((AB).sub.n B).sub.4 type wherein n is an integer of from 1 to 10; and PA0 (iii) at least one olefin-rubbery diene terpolymer; components (ii) and (iii) being present in amounts effective to improve the organic solvent resistance of said composition. The instant composition is useful in the production of extruded sheets and films, and injection or blow molded articles.
