Synthesis of Copolycarbonates by Solid State Polymerization |
| 초록 |
Copolycarbonates containing the birefringence reducing units have become the material of interest for the manufacture of optical data storage media.In the present work, the high molecular weight copolycarbonates containing the birefringence reducing units are prepared by solid state polymerization in three steps. The first step involves the preparation of low molecular weight copolycarbonate prepolymer by the melt polymerization of 2,2-bis(4-hydroxyphenyl)propane (Bisphenol-A) and'-bis(4-hydroxyphenyl)cyclohexane(Bisphenol-Z) with diphenyl carbonate, a second step of crystallizing the copolycarbonate prepolymer and a third step of building the molecular weight of the crystallized copolycarbonate prepolymer by heating to a temperature between the glass transition temperature and the melting temperature in an inert gas atmosphere in the presence of a catalyst. |
