Abstract

According to the present invention, an aromatic polycarbonate resin composition comprising: a resin component (A) mainly comprising an aromatic polycarbonate; a reinforcing agent and/or a filler (B); and an aromatic sulfonic acid and/or an ester thereof (C), wherein a mixture consisting of said component (B) and said component (C) has a pH of 4 to 8 when measured in accordance with JIS-K5101, and said composition comprises 1 to 200 parts by weight of said component (B) and 0.001 to 5 parts by weight of said component (C) based on 100 parts by weight of said component (A) is provided.

Claims (18)

1. An aromatic polycarbonate resin composition comprising:

a resin component (A) comprising more than 50 parts by weight of an aromatic polycarbonate relative to 100 parts by weight of said resin component;

a reinforcing agent and/or a filler (B); and

an aromatic sulfonic acid and/or an ester thereof (C),

wherein a mixture consisting of said component (B) and said component (C) has a pH of 4 to 8 when measured in accordance with JIS-K5101,

said composition comprises 1 to 200 parts by weight of said component (B) and 0.01 to 3 parts by weight of said component (C) based on 100 parts by weight of said component (A), and

the aromatic sulfonic acid and/or the ester thereof is at least one member of the group consisting of benzenesulfonic acid, p-toluenesulfonic acid, xylenesulfonic acid, naphthalenesulfonic acid, diisopropylnaphthalenesulfonic acid, diisobutylnaphthalenesulfonic acid, dodecylbenzenesulfonic acid, methyl benzenesulfonate, ethyl benzenesulfonate, propyl benzenesulfonate, butyl benzenesulfonate, octyl benzenesulfonate, phenyl benzenesulfonate, methyl p-toluenesulfonate, ethyl p-toluenesulfonate, propyl p-toluenesulfonate, butyl p-toluenesulfonate, octyl p-toluenesulfonate, phenyl p-toluenesulfonate, methyl naphthalenesulfonate, ethyl naphthalenesulfonate, propyl naphthalenesulfonate, butyl naphthalenesulfonate, 2-phenyl-2-propyl dodecylbenzenesulfonate and 2-phenyl-2-butyl dodecylbenzenesulfonate.

2. The aromatic polycarbonate resin composition according to claim 1 , wherein said component (B) is at least one member selected from a group consisting of glass fiber, glass flake, carbon fiber, talc and mica.

3. The aromatic polycarbonate resin composition according to claim 1 or 2 , further comprising 0.1 to 30 parts by weight of titanium oxide (D).

4. The aromatic polycarbonate resin composition according to claim 1 or 2 , further comprising 0.01 to 1 part by weight of a fluoropolymer (E).

5. The aromatic polycarbonate resin composition according to claim 3 , furthermore comprising

0.01 to 1 part by weight of a fluoropolymer (E).

6. The aromatic polycarbonate resin composition according to claim 4 , wherein an aqueous dispersion of a fluoropolymer is used as said component (E).

7. The aromatic polycarbonate resin composition according to claim 5 , wherein an aqueous dispersion of a fluoropolymer is used as said component (E).

8. The aromatic polycarbonate resin composition according to claim 1 , wherein said composition comprises 0.01 to 1 part by weight of said component (C) based on 100 parts by weight of said component (A).

9. The aromatic polycarbonate resin composition according to claim 1 , wherein said composition comprises 0.05 to 0.5 part by weight of said component (C) based on 100 parts by weight of said component (A).

10. An injection molded article formed from the aromatic polycarbonate resin composition according to claim 1 or 2 .

11. An extrusion molded article formed from the aromatic polycarbonate resin composition according to claim 1 or 2 .
