ABSTRACT:
The intrinsic viscosity of a high molecular weight aromatic polycarbonate resin is reduced and the melt processability is concomitantly enhanced by the inclusion of a small amount of a fatty acid or acids. The mixture of polymer and acid is more readily extrudable, without detriment to other desirable physical and chemical properties.
