Polycarbonate compositions for reduced splay in combination with sustained or improved impact resistance

A blended polycarbonate composition with improved surface characteristics comprising:

• (a) from about 30 wt % to about 85 wt % of a polycarbonate component;
• (b) from greater than 1 wt % to about 20 wt % of an (isophthalic acid-terephthalic acid-resorcinol)-bisphenol A copolyestercarbonate copolymer;
• (c) from about 10 wt % to about 30 wt % of an impact modifier component;
• and
• (d) from about 5 wt % to about 25 wt % of a filler component;
• wherein all weight percent values are based on the total weight of the composition;
• and
• wherein the composition exhibits a splay at least about 30% less than a splay of a reference composition consisting essentially of from about 30 wt % to about 85 wt % of a polycarbonate component comprising a polycarbonate polymer, a poly(carbonate-siloxane) copolymer, or a combination thereof;
• from about 10 wt % to about 30 wt % of an impact modifier component;
• and from about 5 wt % to about 25 wt % of a filler component.
