Patent ID: 8022166

Claim:
A thermoplastic composition comprising: a polycarbonate polymer (A) having repeating units derived from 2-phenyl-3,3-bis(4-hydroxyphenyl)phthalimidine (PPPBP); a polycarbonate polymer (B) which is different from polymer (A); and an impact modifier (C) which is different from polymer (A) and polymer (B); wherein the thermoplastic composition has a heat deflection temperature of at least 120° C., when measured according to ISO 75; a notched Izod impact strength of at least 20 kJ/m 2 at 0° C., as measured according to ISO 180; and an apparent viscosity of 200 Pa·sec or less, when measured at 320° C. and at a shear rate of 1500 sec −1 .
