Abstract: A polycarbonate composition comprises: a copolycarbonate comprising repeating units derived from a cyclohexylidene-bridged bisphenol; and an auxiliary polycarbonate comprising a branched homopolycarbonate; a poly(1,4-cyclohexanedimethylene terephthalate), a copolycarbonate derived from an isophorylidene-bridged bisphenol, and optionally a poly(alkylene cyclohexanedicarboxylate), poly(carbonate siloxane) having a siloxane content of less than 20 wt % based on the total weight of the poly(carbonatesiloxane), poly(aliphatic ester-carbonate) comprising bisphenol A carbonate units and C6-12 dicarboxy ester units; or a combination thereof. The polycarbonate compositions have one or more of a transparency of 89% or greater on 2.5 mm plaques according to ASTM-D1003-00; and a heat deformation temperature of at least 111° C., or at least 127° C. at 0.45 MPa or at least 98° C., or at least 110° C. at 1.82 MPa as determined on 3.18 mm bars per ASTM D648.

Abstract: Provided are copolycarbonate compositions including a stabilizer package which comprise a phosphorous-containing acid, an ester of phosphorous-containing acid, and an organosulfonic stabilizer where the phosphorous-containing acid and the ester of a phosphorous-containing acid are present in a molar ratio of 1 to 2. The total stabilization package is for example, in the amount by weight of 4 to 32 ppm, 8 to 24 ppm, or 8 to 16 ppm and the organosulfonic stabilizer is, e.g., of 2 to 30 ppm, or 4 to 24 ppm, or 8 to 16 ppm.
