POLYCARBONATE, PROCESS FOR PRODUCING THE SAME, AND MOLDED ARTICLE THEREOF

摘要

A polycarbonate which is stable against thermal decomposition at a temperature range for melt molding without adding a heat resistant stabilizer and suitable for the melt molding of a thin product, production method and molded products thereof. The polycarbonate is comprising mainly a recurring unit represented by the following formula (1), and has a percentage of the total of integrated intensities of all signals detected at four ranges, delta = 2.14 to 2.17 ppm, delta = 3.46 to 3.49 ppm, delta = 3.62 to 3.69 ppm and delta = 5.42 to 5.46 ppm to the integrated intensity of a signal derived from a methyl group detected at a range of delta = 1.50 to 2.00 ppm of 0.01 to 2.0 % in its <1>H-NMR spectrum in heavy chloroform and a viscosity average molecular weight of 10,000 to 100,000.
