More Information
Summary:Polycarbonate resin containing small amounts of carbamate compounds is disclosed. The resin that contains at least one of compounds conforming to wherein R1 and R2 independently of one another denote hydrogen or C1-C12-alkyl, or together denote C4-C12-alkylidene, R3 and R4 independently of one another represent hydrogen, C1-C12-alkyl, or phenyl, or together with the carbon atom to which they are bonded form cyclohexyl or trimethylcyclohexyl, and R5 denotes hydrogen, C1-C12-alkyl, C5-C12-cycloalkyl, phenyl or cumyl, are characterized by their low electrostatic field and therefore suitable for making optical storage media.
