Title:

POLYCARBONATE RESIN COMPOSITION PELLETS AND PROCESS FOR MANUFACTURING SAME

Document Type and Number:

WIPO Patent Application WO/2013/100090

Kind Code:

A1

Abstract:

Polycarbonate resin composition pellets which exhibit a light transmittance of 97.0% or more at a wavelength of 380nm and which have a viscosity-average molecular weight (Mv) of 11,000 to 22,000. The light transmittance is determined by measuring the light transmittance of a methylene chloride solution having a concentration of 12g/dL with the solution put in a quartz glass cell having an optical path length of 5cm.
