본 발명은 투명한 폴리카르보네이트 조성물의 유동성을 증진시키기 위한 적어도 1종의 포스페이트와 조합된 디글리세롤 에스테르의 용도에 관한 것이다. 용융 점도 및 용융 체적 유량이 개선된다. 또한, 디글리세롤 에스테르는 또한 상기 조성물의 투과율을 증가시키고 황색 지수를 감소시킴으로써 광학 특성에 긍정적인 효과를 갖는다. 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.
