Description

526236 A7 B7 V. Description of the Invention (i) [Technical Field] The present invention relates to an aromatic polycarbonate composition and an injection molded product thereof. In more detail, the present invention relates to an aromatic polycarbonate composition having excellent transparency, hue stability, and retention stability during molding, and an injection molded product thereof. [Current technology] Polycarbonate resin has excellent optical characteristics, electrical characteristics, dimensional stability, and self-extinguishing properties, excellent impact resistance, and mechanical properties such as breaking strength. In addition, 尙 has excellent heat resistance, Because of its properties such as transparency, it is widely used for a wide range of applications. In addition, because of its transparency, it is also used in a large number of applications such as lenses, cymbals, optical discs, sheets, and films. Especially for the use of optical resins such as lenses and optical discs, molded articles are often required to have excellent transparency and hue. Specifically, it is often required to have retention stability during molding of the resin composition, that is, thermal stability during retention, hue stability, and the like, and moldability during molding, that is, to give the same shape and size as the design. Reproducibility, release characteristics, etc. In addition, molded products are also required to have environmental stability such as wet heat durability. In the manufacture of polycarbonate resin compositions, fatty acid esters are generally used as release agents. This release agent, especially in the manufacture of precision molded products such as optical discs, can generally improve the release properties of the mold and the molded product, and only slightly inhibits the reduction of the hue, transparency, and surface properties of the molded product, such as physical properties. However, among the characteristics of fatty acid ester compounds, in addition to having a better paper size, the Chinese National Standard (CNS) A4 specification (210X29 * 7 mm) is applicable.-(Please read the precautions on the back before filling in this Page) Ordering Bureau, Ministry of Economic Affairs, Smart Finance 4 Bureau 3 (Printed by Industrial and Consumer Cooperatives-4-526236 A7 B7) 5. Description of the invention (2) In addition to mold release, 尙 has low heat resistance and is prone to thermal decomposition. It is a fatty acid ester release agent. In the presence of acidic or basic compounds or metal compounds, the molding temperature of polycarbonate resin, especially when it exceeds 340 V, will cause decomposition and reduce the release energy, or If it is more severe, problems such as coloring of the molded article and contamination of the molding die may occur. In the production method of polycarbonate resins, for example, a method of directly reacting phosgene with an aromatic dihydroxy compound (interfacial polymerization method) is known. ), Or a method of transesterifying an aromatic dihydroxy compound with a diaryl carbonate such as diphenyl carbonate in a molten state (melting method), etc. Used in the interfacial polymerization method In order to solve the above problems, polycarbonate resins are generally subjected to various refining treatments. In addition to reducing impurities in the resin, various stabilizers are used to reduce the degree of decomposition of the release agent described above. In recent years, the emergence of new specifications of DVD optical discs has made the optical disc substrate must be molded at a higher temperature than 35 (TC. Or higher). Therefore, when the substrate is molded, the release agent or the resin composition is decomposed, or New problems such as coloring. In the polycarbonate manufacturing method of the melt-producing method that performs the transesterification reaction, in order to improve the manufacturing efficiency, it is generally used according to the content described in documents such as "Plastic Materials Lecture 17 Polycarbonate" (pages 48 to 53). Transesterification catalyst.

Description of the invention (3) The properties and hue are improved, the generation of branched chains in the polymer molecules is reduced, the quality such as fluidity is improved, and foreign bodies such as colloids are not generated. However, the polycarbonate resin in the melt polymerization method, because of the side reaction activity derived from the alkali metal compound used as the transesterification catalyst or various additives, makes it in high temperature environment, oxidizing environment or hydrolysis conditions. The stability is extremely unstable. In addition, the release agent added as a precision molding additive may cause decomposition as described above, so when compared with the polycarbonate resin or the resin composition of the interfacial polymerization method, the release agent may There are problems that fail to show the original effect. In order to solve these problems, Japanese Unexamined Patent Publication No. 4-328 1 24 and Japanese Unexamined Patent Publication No. 4-328 1 56 describe a method of using a sulfonic acid ester-containing acidic compound to neutralize a transesterification catalyst. Further, Japanese Patent Application Laid-Open No. 8-59975 discloses a proposal for using a sulfonic acid scale salt, a phosphite compound or a phenol antioxidant. In Japanese Patent Application Laid-Open No. 4-3 6346, it is described that an aromatic organic dihydroxy compound and a carbonic acid diester are used in order to use a nitrogen-containing basic compound (a) and an alkali metal-containing compound or an alkaline earth metal compound (b ) Catalyst catalyst, or (a) and (b) catalyst catalysts containing boric acid or boronic acid ester as described above, undergo transesterification reaction in a molten state to obtain 100 parts by weight of aromatic polycarbonate resin and Phosphorus oxidation inhibitor 0.005 to 0.5 parts by weight of an aromatic polycarbonate resin composition. In the above-mentioned melt polymerization method polycarbonate resin, when a fatty acid ester-based release agent is used to mold a precision molded product, the release agent and the like may cause side reactions such as decomposition, and the expected release performance cannot be sufficiently obtained.
