Abstract
Copolyester-carbonate resin containing composition comprising, in physical admixture: PA1 (i) at least one aromatic copolyester-carbonate resin; PA1 (ii) at least one aromatic polycarbonate resin; PA1 (iii) at least one amorphous polyester resin; and PA1 (iv) at least one polymer selected from PA2 (a) an olefin acrylate copolymer, PA2 (b) a polyolefin, and PA2 (c) an olefin diene trepolymer. This composition contains amounts of components (ii)-(iv) effective to improve the resistance to mild organic solvents and the impact properties of the copolyester-carbonate resin.
