Title (EN) POLYCARBONATE COMPOSITIONS AND ARTICLES COMPRISING THE SAME
(FR) COMPOSITIONS DE POLYCARBONATE ET ARTICLES LES COMPRENANT
Abstract: front page image
(EN)This invention relates to polycarbonate compositions and articles comprising the same. The polycarbonate compositions comprise the following components: A) from 75 wt.-% to 97.5 wt.-% of a polycarbonate, B) from 1.5 wt.-% to 15 wt.-% of a flow promoter selected from alicyclic hydrocarbon resins, and C) from 1 wt.-% to 15 wt.-% of an impact modifier, in each case based on the total weight of the composition; wherein the composition comprises no polycarbonate-polysiloxane copolymer. The polycarbonate compositions of the present invention have good coating resistance, chemical resistance and impact properties as well as better flowability.
(FR)Cette invention concerne des compositions de polycarbonate et des articles les comprenant. Les compositions de polycarbonate comprennent les constituants suivants : A) de 75 % en poids à 97,5 % en poids d'un polycarbonate, B) de 1,5 % en poids à 15 % en poids d'un promoteur d'écoulement choisi parmi les résines d'hydrocarbures alicycliques, et C) de 1 % en poids à 15 % en poids d'un agent anti-choc, dans chaque cas par rapport au poids total de la composition; la composition ne comprenant pas de copolymère polycarbonate-polysiloxane. Les compositions de polycarbonate de la présente invention ont de bonnes propriétés de résistance de revêtement, de résistance chimique et d'impact ainsi qu'une meilleure aptitude à l'écoulement.
