High heat polycarbonate compositions

An article comprising a metallized surface and a thermoplastic composition comprising, based on the total weight of the composition:

• (a) 35 wt % to 72 wt % of a first polycarbonate which is a para-cumylphenol end-capped polycarbonate comprising 31 mol % to 35 mol % structural units derived from 3,3-bis(4-hydroxyphenyl)-2-phenylisoindolin-1-one and at least 18 wt % structural units derived from bisphenol A, the first polycarbonate having a Mw of 23,000 g/mol [±1,000 g/mol] to 40,000 g/mol [±1,000 g/mol], as determined by GPC using BPA polycarbonate;
• and
• (b) a second polycarbonate that is a para-cumylphenol end-capped bisphenol A polycarbonate having a Mw of 17,000 g/mol [±1,000 g/mol] to less than 20,000 g/mol, as determined by GPC using bisphenol A polycarbonate standards;
• wherein the composition has a melt viscosity of less than 375 Pa·s, measured in accordance with ISO 11443 at 300° C. at a shear rate of 1500 s−1;
• a heat deflection temperature of at least 150° C., measured at 0.45 MPa in accordance with ISO 75;
• and
• the metalized article achieves a GT0 metal adhesion rating when measured in accordance with ASTM 3359/ISO 2409;
• and
• wherein the article is selected from instrument panels, overhead consoles, interior trim, center consoles, panels, quarter panels, rocker panels, trim, fenders, doors, deck lids, trunk lids, hoods, bonnets, roofs, bumpers, fascia, grilles, minor housings, pillar appliqués, cladding, body side moldings, wheel covers, hubcaps, door handles, spoilers, window frames, headlamp bezels, headlamps, tail lamps, tail lamp housings, tail lamp bezels, license plate enclosures, roof racks, circuit breakers, electrical and electronic housings, and running boards, or any combination thereof.
