Document Type and Number:
Japanese Patent JP2001354781
Kind Code:
A
Abstract:
To provide a window material consisting of a polycarbonate resin which remains less strain and is excellent in strength and resistance to deterioration in the environment.
The window material is obtained by an injection molding of a polycarbonate resin (A component) which has a molecular weight distribution Mw/Mn, obtained by dividing the weight average molecular weight (Mw) in terms of a standard polystyrene measured by the GPC(Gel Permeation Chromatography) method, by the number average molecular weight (Mn) of 1.5-3.0 and a viscosity average molecular weight of 15,000-26,000.
