MOLDED OPTICAL ARTICLES CONTAINING A SULFONIC ACID ESTER COMPOUND WITH EXCELLENT OPTICAL PROPERTIES PREPARED FROM POLYCARBONATE-BASED RESIN AND A METHOD FOR PREPARING THE SAME

摘要

PURPOSE: Molded optical articles are provided to ensure excellent optical properties such as color coordinate and brightness, and excellent physical properties such as thermal stability, color stability, anti-hydrolysis property.;CONSTITUTION: Molded optical articles are manufactured from a polycarbonate resin composition. The polycarbonate resin composition comprises a molten polycarbonate resin and at least one sulfonic acid ester compound represented by chemical formula 1. In chemical formula 1, R1 and R3 are C1~20 hydrocarbon radical or halogen-substituted C1~20 hydrocarbon radical; R2 is C1~20 hydrocarbon radical, halogen-substituted C1~20 hydrocarbon radical or C1~20 glycol group in which the number of oxygen is 1~10; and n is an integer of 0~5.;COPYRIGHT KIPO 2011
