Abstract (en)

[origin: WO9963002A1] A thermoplastic resin comprising a miscible resin blend of a ductile resin containing greater than about 60 percent by weight repeating units of an aryl polycarbonate, and a polyester resin wherein ratio of polyester resin to ductile resin is from about 60 to 40 to about 85 to about 15, wherein the polyester consist essentially of a polyester having formula (I) where R and R<1> are cycloalkyl or cycloalkyl containing radicals. Preferred are blends of an aromatic polycarbonate or a polyestercarbonate and a cycloaliphatic polyester like poly(1,4-cyclohexanedimethylene-1,4-cyclohexane dicarboxylate) stabilized with acidic phosphorus compounds.
