Abstract: A replication composition includes at least 45 weight percent (wt) of a polycarbonate; 3 to 55 wt % of a polyester comprising a poly(C1-6 alkylene) terephthalate or a polyester comprising repeating units of Formula I: (I); wherein each T is independently a C5-7 cycloaliphatic group or C6-12aromatic group, and each D is independently a C6-12 aromatic group or C2-12 aliphatic group, provided that at least 50 mole percent of D is a 1,4-cyclohexanedimethyl group or a C2-12 aliphatic group; wherein the polyester has a melt viscosity between 0.01 and 3,000 poise (0.001 and 300 Pa·s) measured at 1500/seconds shear rate, at a temperature of 275° C.; and 0.01 to 4 wt % additives; wherein the weight percentages are based on 100 wt % of the composition.
