    摘要: Weatherability of polycarbonates, or of blends of polycarbonates with other polymers such as polyesters, is improved by incorporating therein a thermoplastic arylate polymer comprising units derived from a resorcinol or alkylresorcinol isophthalate-terephthalate. These units may be combined with units derived from a resorcinol or alkylresorcinol ester of a C.sub.4-12 aliphatic, alicyclic or mixed aliphatic-alicyclic dicarboxylic acid, such as sebacic acid.

    摘要: Weatherable polycarbonate compositions (formulations or blends) comprise at least one of a piperazinone and piperazine dione based HALS, and polyether based. The combination of these HALS and polyether based polymers exhibits a synergy that results in enhanced protection of the polycarbonate compositions by imparting photostability to the polycarbonate formulations, thereby reducing yellowing or other forms of light induced degradation.

    摘要: An optoelectronic device assembly can comprise: a coated element and an electroactive cell on the coated element, wherein the electroactive cell is selected from the group consisting of a light emitting diode and a photovoltaic cell. The coated element can comprise: transparent thermoplastic substrate and a protective weathering layer. The transparent thermoplastic substrate can comprise a material selected from the group consisting of aromatic polycarbonate and polyester, and combinations comprising at least one of the foregoing materials. The protective weathering layer can have a UV absorbance loss rate at 330 nm of less than or equal to 0.15 A/year as estimated from filtered xenon arc exposure and/or having a rate of erosion of less than or equal to 5 μm per year as estimated from filtered xenon arc exposure.
