<p>The present invention is an ignition resistant carbonate polymer composition, a method to make said composition and fabricated articles made therefrom. The ignition resistant carbonate polymer composition consists of: (i) an aromatic polycarbonate or an aromatic polyester carbonate, (ii) a graft (co)polymer produced by mass polymerization, (iii) a silicon-containing graft (co)polymer having a core-shell morphology, including a grafted shell that contains polymerized alkyl(meth)acrylate and a composite rubber core that contains polyorganosiloxane and poly(meth)alkyl acrylate components, wherein said core comprises at least 20 percent by weight silicon based on the total weight of (iii), (iv) an oligomeric aromatic phosphate compound represented by the formula I: wherein, R1, R2, R3 and R4 independently of one another each denote optionally halogenated C1- to C8-alkyl, or C5- to C6- cycloalkyl, C6- to C20- aryl or C7- to C12- aralkyl, in each case optionally substituted by alkyl and/or halogen, X denotes a mono- or polynuclear aromatic radical having 6 to 30 C atoms, n independently of one another is 0 or 1, N represents values greater than 0 and less than 30, (v) a polytetrafluoroethylene polymer, a fluorothermoplast, or mixture thereof, and (vi) one or more of a thermoplastic vinyl (co)polymer, an impact modifier different from (iii), a filler, a reinforcing material, a stabilizer, a pigment, a dye, a mold release, a lubricant, or an anti-static agent.</p> |
