Patent
CA 2386934
A light guide plate which comprises (A) a copolyester carbonate having one or more aliphatic segments; and a light guide plate which comprises a polycarbonate resin composition comprising (A) a copolyester carbonate having one or more aliphatic segments and (B) an aromatic polycarbonate. The polycarbonate resin composition has improved flowability while retaining high mechanical strength.
L'invention se rapporte à une plaque de guidage optique qui comporte (A) un carbonate de copolyester ayant un ou plusieurs segments aliphatiques; et à une plaque de guidage optique qui comporte une composition à base de résine de polycarbonate comportant (A) un carbonate de copolyester ayant un ou plusieurs segments aliphatiques et (B) un polycarbonate aromatique. La composition à base de résine de polycarbonate présente une aptitude à l'écoulement améliorée tout en conservant une grande résistance mécanique.
