Abstract
Novel compositions with high resistance to environmental stress cracking and crazing comprise: PA0 (a) an aromatic carbonate polymer; and PA0 (b) a modifer combination therefor comprising: PA1 (i) a 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 of the A--B--A'; A--(B--A--B).sub.n --A; 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 from 1 to 10; PA1 (ii) an olefin-acrylate or methacrylate copolymer, alone, or in further combination with PA1 (iii) a polyolefin.
