A resin composition comprising an aromatic polycarbonate resin having excellent transparency and flame retardancy. The resin composition comprises 100 parts by weight of an aromatic polycarbonate resin having a branched structure with a branching ratio of 0.7 to 1.1 mol % (component A) and 0.005 to 12 parts by weight of at least one flame retardant.

Aromatic polycarbonate resin composition

A resin composition consisting of: A process of manufacturing the resin composition and a method of preventing the melt dripping during combustion of the resin composition. The flame retardancy of the above aromatic polycarbonate resin composition comprising the fluorine-containing organic metal salt compound is improved.

Aromatic polycarbonate resin composition and manufacturing process thereof

A process for the production of an aromatic phosphorus-containing polymer, comprising (i) reacting phosphorus pentachloride with an aromatic dihydroxy compound and then reacting the reaction product with an aromatic monohydroxy compound, or (ii) allowing phosphorus pentachloride, an aromatic dihydroxy compound and an aromatic monohydroxy compound to react concurrently, to form an intermediate polymer, and then hydrolyzing the intermediate polymer, the above process being capable of giving an aromatic phosphorus-containing polymer in the absence of a catalyst for a short period of time at a relatively low temperature.

Process for the production of aromatic phosphorus-containing polymer

There is provided a fire retardant polycarbonate resin composition comprising a polycarbonate resin, a specific partially esterified phosphoric acid metal salt and a specific partially esterified phosphoric acid in specific proportions. The polycarbonate resin composition can provide a transparent molded article which are excellent in fire retardance and heat stability.
