| titleOfInvention | Method for producing polycarbonate having high fluidity |
| abstract | The present invention relates to a high-flow polycarbonate manufacturing method, the production method according to the invention is characterized in that the polycondensation of polycarbonate oligomers and polycondensation non-polycondensation reactive polycarbonate oligomer together to produce a high-flow polycarbonate The polycarbonate having no polycondensation reactivity is characterized in that 10 to 25% by weight of the total oligomer.n n n By using the method of manufacturing a highly flexible polycarbonate according to the present invention, the polycarbonate oligomer is transformed into an inactive form and polycondensed into a polymer together with a reactive oligomer to maximize the advantages of the existing polycarbonate. By maintaining the viscosity in the molten state while maintaining the fluidity increases 30% ~ 50% than the conventional polycarbonate, the processing temperature can be produced polycarbonate lower than 10 ℃. Since the polycarbonate having high fluidity can be formed into a thin film, the polycarbonate prepared according to the present invention can be used for manufacturing a complicated structure and a thin molding. In particular, it can be used in various materials such as optical disks, films, and the like, such as voice communication, image storage, and information storage, such as portable communication devices, notebooks, and desktop computers. In addition, changes in color tone and gas generation due to deterioration of low molecular weight during processing, which are problems caused by blends or compounds of low molecular weight materials, can be solved. |
