실험 절차

2371 Parts of deionized water, 156 parts of a 48.5% aqueous sodium hydroxide solution, and 0.6 parts of hydrosulfite were placed in-the same apparatus as used in Example 1, and after deoxidation was carried out in the same way as in Example 1, 157.6 parts of bisphenol AF of 99.98% purity and 134.6 parts of bisphenol FL of 99.8% purity were dissolved therein, then 2548 parts of methylene chloride was added, and 98.5 parts of phosgene was blown thereinto at 13° to 16° C. over about 50 min with stirring. Then, 53.2 parts of a 48.5% aqueous sodium hydroxide solution and 8.5 parts of p-tert-butylphenol were added and after they were emulsified by stirring, 0.2 parts of triethylamine was added, followed by stirring at 30° C. for about 2 hours, to complete the reaction. Then the reaction mixture was treated in the same way as in Example 1, to obtain a copolymerized polymer. The specific viscosity of this copolymerized polymer was 0.178, the retention of the specific viscosity after the steam treatment was 85% and the glass transition temperature was 215° C., which show high hydrolysis resistance and high heat resistance, the light transmittance was 89%, which is good, the light transmittance after the heat treatment was 89%, showing excellent heat stability; and the oxidation resistance was remarkably excellent in comparison with the polymer obtained from bisphenol A as shown by curve 3 (.diamond.) in FIG. 2.
