Abstract
A thermoplastic composition comprises a copolycarbonate comprising 25 to 100 mole percent of a first carbonate unit derived from a dihydroxy aromatic compound having the formula wherein Rand Rare Calkyl, T is a Ccycloalkylene, a Ccylcloalkylidene, a Calkylene, a Calkylidene, a Carylene, a Carylalkylene, Carylalkylidene, a Calkylarylene, or a Carylenealkyl, and r and s are each independently 1 to 4, and r and s are 1 to 4; and 0 to 75 mole percent of a second carbonate unit, wherein the first carbonate unit and second carbonate unit are not identical; a polysiloxane-polycarbonate copolymer comprising 0.15 to 30 weight percent of a polysiloxane block comprising siloxane units of the formula wherein E is on average of 4 to 60 units, and 70 to 99.85 weight percent of a third carbonate unit, wherein an article having a thickness of 3.2 mm and molded from the thermoplastic composition has a Dynatup total energy of greater than 50 Joules, as measured at a constant speed of 3.3 to 3.6 m/sec at 23° C. according to ASTM D3763-02. A method of making and articles prepared therefrom are also disclosed.
