Abstract
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.
