Abstract
The present invention relates to the use of diglycerol esters for enhancing the flowability of transparent polycarbonate compositions. Melt viscosities and melt volume flow rates are improved. In addition, the diglycerol esters also exert a positive effect on the optical properties by increasing the transmission of the compositions and reducing the yellowness index.
