POLYCARBONATE RESIN COMPOSITION HAVING EXCELLENT PERMEABILITY AND COLOR STABILITY WHILE HAVING EXCELLENT MECHANICAL STRENGTH AND PROCESSABILITY WORKABILITY

摘要

PURPOSE: A polycarbonate resin composition is provided to improve physical properties and processability workability by using a sufficient amount of two polycarbonate resins having different weight average molecular weight from each other.;CONSTITUTION: A polycarbonate resin composition includes a first polycarbonate resin with a weight average molecular weight (Mw) of 10,000-24,900 g/mol; and a second polycarbonate resin with a weight average molecular weight of 25,000-50,000 g/mol. The first polycarbonate resin and the second polycarbonate resin are a polycarbonate resin including a bisphenol, a phosgene, or a carbonic acid diester. The amounts of the first polycarbonate resin and the second polycarbonate resin are respectively 70-99 wt% and 1-30 wt%.;COPYRIGHT KIPO 2013
