Abstract:
1. An article having a metallized surface formed by vacuum metallization comprising an extruded composition comprising: a. a thermoplastic polyester selected from the group consisting of polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, polybutylene naphthalate, polytrimethylene terephthalate, poly(1,4-cyclohexylenedimethylene 1,4-cyclohexanedicarboxylate), poly(1,4-cyclohexylenedimethylene terephthalate), poly(cyclohexylenedimethylene-co-ethylene terephthalate), and combinations thereof; and based on 100 parts by weight of the polyester, b. 5 to 15 parts by weight of a polycarbonate, wherein the polycarbonate comprises a carbonate component and a diphenol component, wherein said diphenol component is selected from the group consisting of 2,2-bis(4-hydroxyphenyl)propane, 2,2-bis(3,5-dimethyl-4-hydroxyphenyl)propane, 1,1-bis(4-hydroxyphenyl)cyclohexane, 1,1-bis(3,5-dimethyl-4-hydroxyphenyl)cyclohexane, 1,1-bis(4-hydroxyphenyl)decane, 1,4-bis(4-hydroxyphenyl)propane, 1,1-bis(4-hydroxyphenyl)cyclododecane, 1,1-bis(3,5-dimethyl-4-hydroxyphenyl)cyclododecane, 4,4-dihydroxyldiphenylether, 4,4-thiodiphenol, and 4,4-dihydroxy-2,5-dihydroxydiphenylether, and combinations thereof; c. 0.05 to 0.5 parts by weight of an inorganic phosphorous compound; d. 0.2 to 0.7 parts by weight of an alkali metal salt, an alkaline earth metal salt, and/or a C e. 0.05 up to 2 parts by weight of particulate filler, wherein the particulate filler has an average particle size less than or equal to 10 μm; and optionally, f. 0.001 to 2 parts by weight of a colorant; wherein the metallized surface retains 90% or more of its gloss after heat aging at 150° C. for 1 hour, measured at 20 degrees using a micro tri gloss meter.
