Title
(EN) REDUCED COLOR POLYCARBONATE COMPOSITIONS, METHODS OF MANUFACTURE, AND ARTICLES THEREOF
(FR) COMPOSITIONS DE POLYCARBONATE DE COULEUR RÉDUITE, PROCÉDÉS DE PRÉPARATION ET ARTICLES ASSOCIÉS
Abstract
(EN) A method of preparing a polycarbonate composition, including: melt polymerizing in a polymerization unit a dihydroxy compound with a diaryl carbonate and removing a stream of color inducing species containing an isopropenyl phenyl-containing group from the polymerization unit, to form a polycarbonate composition, wherein the polycarbonate has a color inducing species containing an isopropenyl phenyl-containing group level below 170 ppm is provided.
(FR) L'invention concerne un procédé de préparation d'une composition de polycarbonate, comprenant : la polymérisation à l'état fondu dans une unité de polymérisation d'un composé dihydroxy avec un carbonate de diaryle et l'élimination d'un flux d'espèces induisant une couleur, contenant un groupe contenant isoprényl-phényle provenant de l'unité de polymérisation, pour former une composition de polycarbonate, le polycarbonate présentant des espèces induisant une couleur contenant un niveau de groupe contenant isoprényl-phényle inférieur à 170 ppm.
