ABSTRACT:
An optical data storage comprising a thermoplastic copolycarbonate is disclosed. The copolycarbonate contains at least one unit derived from dihydroxydiphenyl ether and at least one unit derived from at least one member selected from the group consisting of 4,4′dihydroxybiphenyl and 1,1-bis-(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane.
