| titleOfInvention | Method of producing polycarbonate articles by rotation molding and rotation molded articles made by the method |
| abstract | A method for making a polycarbonate article is described wherein the article is made by rotation molding a melt polycarbonate having a weight average molecular weight from 25,000 to about 36,000. The melt polycarbonate is produced by transesterifying a diaryl carbonate and a dihydroxy compound in the presence of a catalyst system to form an intermediate aromatic polycarbonate, wherein the catalyst system comprises a first catalyst selected from the group consisting of alkali metal salts and alkaline earth metal salts; and a second catalyst selected from the group consisting of quaternary ammonium compounds and quaternary phosphonium compounds; adding to said intermediate aromatic polycarbonate a catalyst quencher, and rotation molding the aromatic polycarbonate at a temperature from about 305°C to about 360°C. Also disclosed are polycarbonate light diffusive articles produced by rotation molding. |
