[Industrial Application Field] The present invention relates to a polycarbonate resin composition,
Specifically, the present invention relates to a polycarbonate resin composition containing glass fiber and having excellent flame retardancy and moldability. [Prior Art and Problems to be Solved by the Invention] It has been known that the mechanical strength and heat resistance of polycarbonate resin can be improved by blending glass fibers with polycarbonate resin. However, when glass fiber is blended with polycarbonate resin, there is a problem in that the resulting composition has reduced fluidity, resulting in insufficient moldability. In recent years, a polycarbonate resin composition with good moldability has been developed by mixing polycarbonate having a specific end group with glass fiber (Japanese Patent Application Laid-open No. 133149/1983). However, even with the above polycarbonate resin composition, the flow value is as low as 2.32 x 10 -2 ml/sec, and it is still difficult to say that it is satisfactory in terms of moldability. [Means for Solving the Problems] The present inventor has solved the above-mentioned disadvantages when glass fiber is mixed with polycarbonate resin, and has created a resin that has good fluidity and moldability, as well as flame retardancy and heat resistance. We conducted extensive research to develop a composition with excellent properties. As a result, a composition obtained by mixing glass fiber with a new polycarbonate composed of two specific types of repeating units and having a pentahalogenophenoxy group at the terminal position can achieve the objective. I discovered that. The present invention was completed based on this knowledge. That is, the present invention is based on the formula (A)
