20090069489 | POLYCARBONATE-POLY(ESTER-ETHER) COPOLYMER COMPOSITION, METHOD OF MANUFACTURE, AND ARTICLES THEREFROM - A composition comprises, based on the total weight of the composition, from 5 to 95 weight percent of a polycarbonate and from 5 to 95 weight percent of a poly(ester-ether) copolymer. The poly(ester-ether) copolymer comprises units derived from terephthalic or a chemical equivalent thereof, units derived from butane diol or a chemical equivalent thereof, and 23 to 70 weight percent of units derived from poly(oxytetramethylene) glycol or a chemical equivalent thereof, based on the weight of the copolymer. The composition also comprises from 0.001 to 0.5 weight percent of a quencher. The composition exhibits a Shore D in the range of 45 to 75; and a low temperature notched Izod ductility of at least 80% at −40° C., as measured by ASTM D256. | 03-12-2009 |

20140063831 | METHODS OF MAKING AND ARTICLES COMPRISING A YELLOWING RESISTANT POLYCARBONATE COMPOSITION - Disclosed herein are methods and compositions of polycarbonate blends having, among other characteristics, improved heat resistance. The resulting polycarbonate blends, comprising a first polycarbonate comprising structural repeating units derived from bisphenol acetophenone and optionally a second polycarbonate polymer comprising structural repeating units derived from bisphenol A, can be used in the manufacture of articles while still retaining the advantageous physical properties of blended polycarbonate compositions with improved heat resistance. The disclosed polycarbonate blends optionally comprise one or more polycarbonate blend additives. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention. | 03-06-2014 |
