Title:
POLYCARBONATE RESIN COMPOSITION AND RETARDATION FILM
Document Type and Number:
Japanese Patent JP2006143832
Kind Code:
A
Abstract:
To provide an aromatic polycarbonate resin composition excellent in high transparency and processability.
The aromatic polycarbonate resin composition is obtained by mixing (A) 100 pts.wt. of an aromatic polycarbonate copolymer comprising, for example, a repeating unit (A1) represented by formula (3) and a repeating unit (A2) represented by formula (4), wherein the ratio of the unit (A1) to the unit (A2) is in the range of (A1):(A2)=5:95-95:5 in a molar ratio, with (B) 5-90 pts.wt. of a hydrocarbon resin selected from a rosin resin, a coumarone resin, a coumarone-indene resin and a petroleum resin.
