Polycarbonate compositions incorporating long chain alkylphenol endgroups, for example cardanol, show enhanced pit replication characteristics when molded into optical disks. The enhancement in molding performance is especially pronounced at the shortest mold cycle times tested. Thus, a blend of 75 parts by weight bisphenol A polycarbonate 92 percent encapped with phenol, and 25 parts by weight bisphenol A polycarbonate about 100 percent endcapped with cardanol showed enhanced pit replication performance in optical disk molding trials relative to the same bisphenol A polycarbonate alone and analogous blends utilizing short chain alkylphenols.
