    摘要: The invention relates to substantially single phase silicone copolycarbonates suitable for use in optical articles such as digital versatile disks. The silicone copolycarbonates contain residues of silicone containing and nonsilicone containing bisphenols and have properties particularly suited for use in high density optical data storage media. The invention further relates to the preparation and properties of substantially single phase silicone copolycarbonates having either a blocky or a random structure. The structure of the compositions of the invention is determined by the method of preparation used and may be used to control physical properties.
