Abstract

Patente de Invenção: "COMPOSIçãO DE POLICARBONATO RESISTENTE à RADIAçãO GAMA". Uma composição de moldagem de policarbonato termoplástica tendo uma resistência aperfeiçoada a amarelecimento induzido por radiação gama é mostrada. Particularmente apropriada para a fabricação de dispositivos cambeados para aplicações médicas, a composição contém uma quantidade aditiva de um acetal cíclico estabilizante de um glicerol monoéster conformando-se estruturalmente à Fórmula (I) onde R~ 1~ representa um grupo C~ 1-30~ alquila e R~ 2~ representa um grupo arila.
