(Problems to be Solved by Conventional Techniques and Inventions) Aromatic polycarbonate resins are known to have excellent thermal, electrical, and mechanical properties, especially impact resistance, but have a large molecular weight. As the melt viscosity becomes extremely large, molding conditions such as molding temperature and molding pressure need to be relatively large, which not only has the disadvantage of inferior melt moldability, but also aromatics which are widely used at present. Polycarbonate resin is 2,2-bis- (4
-Hydroxyphenyl) propane (bisphenol A)
The glass transition temperature is approximately 145 ℃ if the viscosity average molecular weight v is 16,000 or more
However, even if the viscosity average molecular weight v increases, the glass transition temperature does not exceed 150 ° C., and the glass transition temperature is low among amorphous resins (transparent resins).

Conventionally, various improvements have been made to enhance the melt-molding processability of an aromatic polycarbonate resin. For example, a polycarbonate resin is produced in the presence of 0.01 to 0.5 mol% of a phenol having two or more reactive hydroxy groups as a branching agent, and the flowability is improved to improve the melt processability (Japanese Patent Laid-Open No. 48-693). However, the use of a branching agent causes the resin to become non-Newtonian and has a disadvantage that the orientation of the molded product becomes non-uniform even if the fluidity is enhanced, and is particularly unsuitable for optical molded products.

Various improvements have also been made to increase the glass transition temperature of the aromatic polycarbonate resin. For example,
An attempt is made to increase the glass transition temperature by mixing with a polyether or polyester (for example, see JP-A-52-5144).
5) It has been proposed. However, the resin composition obtained in this manner is generally opaque, and thus is unsuitable for optical molded articles and the like. On the other hand, in order to improve this opacity, it is attempted to increase the glass transition temperature by copolymerizing with polyether or polyester (for example,
Japanese Patent Application Laid-Open No. 62-156126) has been proposed, but has the disadvantage that complicated polymerization must be carried out and the energy cost is high.
