Beschreibung
Zusammenfassung:	Polycarbonate resin compositions containing (A) 100 wt. parts polycarbonates preferably having a viscosity-average molecular weight of 12,000 SIMILAR 18,000, and (B) 0.001 SIMILAR 5 wt. parts alpha -olefin oligomers, in which the polycarbonates are products of melt polymerization of aromatic dihydroxy compounds with carbonate diesters, are provided. These resin compositions are characterized by good mold release and thermal stability, and very little discoloration or molecular weight lowering during molding.
