Title (EN) DIMENSIONALLY STABLE POLYCARBONATE ARTICLES
(FR) ARTICLES POLYCARBONATE A DIMENSIONS STABLES
Abstract: front page image
(EN)The disclosure relates to articles using polycarbonates produced by a melt transesterification polymerization method using bis(hydroxyaryl)cyclohexanes. Such polycarbonates have suitable glass transition temperatures and outstanding dimensional stabilities, thus making them particularly useful for making articles possessing high temperature stability, particularly for use in optical articles such as high density optical data storage and recordable media.
(FR)La présente invention concerne des articles comprenant des polycarbonates produits par un procédé de polymérisation par transestérification en fusion au moyen de bis(hydroxyaryl)cyclohexanes. Ces polycarbonates ont des températures de transition vitreuse appropriées et d'excellentes stabilités dimensionnelles, ce qui les rend particulièrement utiles pour la réalisation d'articles stables à haute température, notamment pour l'utilisation dans des articles optiques tels que des supports optiques d'enregistrement et de stockage de données à densité élevée.
