Abstract
A flame retardant aromatic polycarbonate resin composition comprising:(1) 100 parts by weight of resin components comprising 50 to 100 wt % of an aromatic polycarbonate resin (component A-1), 0 to 50 wt % of a styrene-based resin (component A-2) and 0 to 50 wt % of an aromatic polyester resin (component A-3); and(2) 0.1 to 10 parts by weight of a silicone compound (component B) which contains an Si—H group and an aromatic group in the molecule based on 100 parts by weight of the total of the resin components, whereinthe silicone compound is at least one selected from silicone compounds which have (1) an Si—H group content (Si—H content) of 0.1 to 1.2 mols/100 g and (2) a content of an aromatic group represented by the following general formula (1) (aromatic group content) of 10 to 70 wt %: wherein X's are each independently an OH group or the residual monovalent organic group having 1 to 20 carbon atoms, and n is 0 or an integer of 1 to 5, with the proviso that when n is 2 or more, X's can differ from one another, and molded articles thereof.A halogen-free polycarbonate resin composition having excellent transparency and dripping preventing properties and molded a…
